The GPS track would take us up Jim Donnelly Trail, a novelty for me, so up we went. Oh my god, I could not imagine how much effort had gone into that trail! I learned from Paul (pliebenberg) later when we talked to him in the parking lot (after he and his wife went to do some trail flagging) that the 2nd Saturday trail crew did most of the work. Thank you, thank you!

I think this was the driest at Coe that I had seen, especially on Kelly Cabin Canyon Trail. It certainly was nice that I came out of the canyon with dry socks, but I kept thinking to myself, we need some rain before the coming trail work day.

I was glad to find that I had not lost all what I'd learned about mountain biking after my long sabbatical. I was still able to ride no-hand on the paved road at the end. I came off my bike at the very last wall on Jackson and had to push 20 yards or so, but that was already better than I had expected. My endurance has regressed though. I used to consider myself lucky for not getting cramps often on long rides, but on this ride (not really a long one), they started on the Cross Canyon climb out. Luckily, I was able to keep them at bay by pedaling delicately (gearing couldn't be high nor too low). The cramps would come on when I got off my bike with my legs extended or when I was crawling. Um, yeah, I crawled under that big fallen tree on Domino Pond trail. Why hadn't Roy (plymmer) ridden though here yet?

Mr. Mud had a little set back on the ride – one screw in his left cleat came out of the worn threads while he was coming down Timm Trail, and we didn't have the right Allen wrench between our two tool sets to loosen up his pedal, which he just (over) tightened yesterday. Being a tough guy he was, he rode all day without being able to unclip the left side when needed to. There were a few low speed tipping overs (hehehe… oops, did I chuckle out loud?), but he pulled it off. On Cross Canyon climb, he pulled away from me. Ok, his endurance shone. But, I beat him on JDT and Anza- Jackson climbs. Oh, on down hills, I always let him pull away from me – drop me to be exact. Not that we compete with each other or anything.

Another wonderful ride. Coe never disappoints. We'll be back!

Oh yeah, it seems that posting rides on Strava is the fad nowadays. Here is mine.

A few photos from my camera. (We've yet to find the micro USB cable for Mud's camera.)

The bike is no longer alone.

The giant fallen tree on Domino Pond Trail. Mud climbed over it, and I crawled under.

That was until… I told Patrick that I would be "back" in 2012. What did that mean? I wasn't really sure. Will I be back to doing those long rides like the 84-mile Tour 'de Peninsula ride, or Everything Skeggs ride, or even the Death Ride??? I don't know, but I got so anxious that as 2012 was approaching, I got a panicky feeling. I had to prepare for my "come back"!

So, I rode my bike almost everyday in the last two weeks of December blessed with the wonderful Bay Area weather.

We got hooked on two fun Skeggs loops so much that we kept going back to them, which I've added to my Skeggs Ride Collection (Rides 7 and 8). And the lengths were short enough for us to go impromptu when things were going a bit slow during the holidays. My interest about mountain biking has been rekindled. Yes, Patrick, I'm back!

But then… I also just got back into rock climbing recently (in the gym mainly, but fairly regularly) after my previous partner Jeanne retired (temporarily) to have a baby. With a new strong partner, I also regained my interest in pushing hard on the climbs.

Yet… the living room is still filled with tools (table saw, chop saw, jig saw, Skil saw, you name it). The walls are wide open and the cats have been having a lot fun walking through them. We probably should get back into our remodeling too; no, we definitely need to. I'm in charge of the house rewiring and still have half of it to go…

Oh, and while framing, an idea suddenly came to me and we now have a short pony wall framed in for my "sewing center". Yep, you heard me right! I'm going to have a sewing center.

Oh, yes, I'm back! Back to what? We shall see. 2012 will tell.

Went to Coe for a day of trail work.  Got there a bit early so I geared up quick so I could go ride the new Jim Donnelly Trail.  This one has a bit of history since it was just "re-aligned" a bit on the sly.  Turns out the guy did a real nice job.  Fun trail that is not super steep but is still challenging.  The trail in places threads through the trees.  The guy has an eye for a good line and I appreciate that.

Got down just as everyone was wrapping up signed the release form and pedaled off for trail work.  One the way there we rode Anza-Jackson to Elderberry.  I got a bit further on Anza-Jackson but still came up short.  Hopefully next time.

We took a bit of a side trip and went and checked out Rock Tower Spring trail which has some cool rock formations and a small bike playground.  Could not do to much since with all the wet the rock was quite slick.

From there we headed on to do our duty.  We made our way down to the top of Cattle Duster and began the work of cutting out the gutters that went straight down the trail in sections and made it a bit sketchy at speed.

Further down I got some good tips from Valerie and Paul on how to build a proper gutter.  How to live in one, I got that.  Building one is something else.  After my second coaching session with Paul I felt I had it.  I spent about 15 minutes with one gutter and in the end liked.  Later riding it confirmed my initial thoughts.

As the day wound down we all headed up the trail to begin the ride out.  First stop was Sierra Vista.  Named so because there is a good view of the Sierra.  Why else.  Then Domino Pond to Cattle Duster.  Ooh, Cattle Duster is now a nice rippen decent.  Whoo Hooo.

We bailed out early as the rest of the group did one more climb.  We had to skedaddle since we had an appointment at Home Depot.

All of the above photos and more (including originals) came from mudworm and mudncrud's cameras and can be found in Mud Gallery.

Extras for the extras:

And there was hard ice at the parking lot when we got there before 10am.

Either the ice was too hard, or Charlie was too light -- he and the bike combined was not able to break the ice! (Um, you might want to turn down your volume before clicking play.)

Two days ago, I sent out an invitation to quite a few people, and on the morning of Black Friday -- the day after Thanksgiving, we were joined by, with MTBR handles in parentheses, Charlie (Skyline35), Patrick (ratpick), Roy (plymmer), Chris (Diesel~), and Jim (Zener) -- yeah, the usual suspects.

Everyone was bracing for freezing temperature, but the frost on Spike Jones Trail was probably the only reminder of our "fear" (as Jim said in his email, "you know how us skinny guys love the cold!"). It was perfect for the climb though as Charlie here would have agreed.

The rest of the ride saw us sun bathe comfortably throughout like here at the top of Timm Trail. That, my friend, I call a perfect temp.

Okay, let me raise the pace a bit because otherwise, I'll never reach the end of the post. Here are a few pictures I took on the ride.

Charlie dropping down Timm Trail:

Here is a trail sign, now where is the trail?

While everyone else is going down Cattle Duster, Chris decided to check out the climb on upper Cattle Duster. To be exact, Roy coaxed him into it. Here, Charlie set up his camera. "Okay, you can go now."

Before long, Chris became a little dot.

I just realized and you might have noticed -- I don't have many close up shots of everyone on the ride. It's not my fault. Most of the time, they were so far ahead of me that no amount of zoom can find them in my view finder anyway. But considering that I was riding with a bunch of guys, there was plenty of chatting on the trail at almost every intersection.

Erik wrote his own ride report . (I think he stole some of my pictures.)

Oh, by the way, it took me a while to put the report up. Well, after the ride, we stopped by a couple of bike shops (no Black Friday sales), went to the gym (for shower), went out for dinner (yummy Korean Tofu Pot), and then hung out with a friend from out of town at a bar. Didn't get home until midnight. This morning? We just got a little too comfortable to get out of bed. All their fault!

It was an agonizingly long day-- a Wednesday -- for him when he bought the bike because he still had to work. But as soon as he got home, after Mango inspected it, he went out for a night ride.

On Friday morning, I offered to go to Skeggs with him early morning before work to take some action shots. Well, it was a misty day. At the famous, photogenic 180 degree turn on Manzanita Trail, this is all I could get:

But the mist seems to add some special effect that we normally don't get. I call it a mysterious feel like this one on Lower Fir:

Even though there was no standing mud puddle at all, the soil got just enough moisture that it was most sticky. After the ride, I gave the Tallboy a sponge bathe (and did not miss any skin) to get rid of the mud. It took me half an hour!

On Thanksgiving Day, a beautiful sunny but crisp day, we went back to Skeggs for a short ride before heading over to our friends' place for dinner. I did get a clean shot at the 180 degree turn, but I'm not Charlie, so the photo left a lot to be desired.

The short ride turned out to be not so short after all. Erik got obsessed with helping a fellow rider fixing his broken chain (we didn't have any power link or connection pin). Took a while, but it was a success story in the end.

On our way home, I told Erik that we should just leave the bikes in my CR-V since we would be going to Coe for a ride the next day. We should just take his FIT to go to the party. He protested.

E: I don't want to leave the bike in the car over night all dark, cold, and lonely...
M: Don't worry, my FTM will be in there as company. Think about it, it'll be cozy. How does that song go? "Just you and me..." Maybe in the middle of the night, the car will start rocking.... hahaha...
E: ...Then someday, we might end up having a 20" BMX bike. Okay!
M: Hmmm... wouldn't that be cute?

P.S. We went to Henry Coe the next day. Charlie, along with many others, was there to take real photos. More details are coming up in my next post...

I had been off my bike for a while because I was completely absorbed in my new job. When I was not thinking about work, I was obsessed with the kitchen remodeling idea that came up a little while ago and had been having fun doing researches on that. But today, after I saw their reports on MTBR, I rushed out the door. Erik and I did a quick ride at Skeggs — still had chores to do before dark to get ready for another busy work week. The condition of the trails we got on (Manzanita, Lower Steam Donkey, Giant Salamander, Lower Fir *gulp*, Resolution, ECdM, etc) was just perfect — tacky and mud free! I wish it could stay like this forever!

So, here… here is the ride:

Oops, wrong link. It was THEIR Hard COEre 100! (I accidentally stole it from Patrick's Garmin Connect.)

And here… here is MY ride:

1 big loop, 100 miles, +20,000 ft of elevation gain and loss.

It even has its own website http://hardcoere100.com/

…

Okay, time for me to fess up… I did not attempt it. But among the near 7 billion people in this over populated world, three men did. Despite their apparent lack of sanity, I'm proud to call them my friends. They were a trio (MTBR handles in parentheses): Dirk (ElHombre), Patrick (ratpick), and Roy (plymmer).  If you, like me, enjoy the pleasure of experiencing others' suffering from the comfort of a chair, you'll enjoy reading their stories:

• Patrick's Plus3 Network report , which I believe was posted before he even arrived home from the ride  (and the ride raised $5.81 for IMBA)
• Dirk's MTBGuru Blog post , with great photos. Ever seen phantoms?
• Roy's MTBR Rundown, a short report for the long ride.

Now, if I did not do this ride, why do I even write this report on it? For the catchy title I guess…. No, of course not! I'm just so impressed with their heroic attempt that I wanted to provide one more access channel in the Cyberspace for their tales to be heard.

As for me, I first dismissed the idea of me ever attempting this ride. (I was quite flattered when Dirk sent me the information.) And then I found myself keep thinking about it — let's see… I've done 8.5 hours of  riding non-stop at Boggs IV, 10 hours of almost non-stop riding solo (during 86mile Tour de Peninsula), and have managed a 7+mph overall speed for 7 hours on my recent All-of-Skeggs (10k+ ascent) bout. I feel that maybe if I pace myself and stay well nourished and hydrated, I might just be able to sustain 100 miles at Coe. Maybe…

On the morning of Oct 16, my alarm clock went off at 2am. By that time, I had been awake and tossing for half an hour. That's unlike me, who normally don't have trouble sleeping. But thoughts were going through my mind. 2am, the trio must be gearing up and rolling out of Hunting Hollow Parking at that exact moment per plan. For me to be rolling at 2am, I have to leave home at 12am. That means I have to get out of bed at 11am. That's the hour when I usually go to bed. So, basically, I will be looking at riding for 100 miles (16 hours if I'm lucky) without any sleep. That's mad. Too mad. No, it was right then and there I made the decision that Hard COEre 100 would never be for me.

Of course, I did not set the alarm for the Hard COEre 100. We were supposed to go to Tahoe area for a day trip. I had wanted to go ride Hole in the Ground (HitG) for a long time, but for one reason or another, we never went. Now the season was nearing the end, I had to make it happen. It was forecast to rain at 90% chance for Sunday, so we would do a day trip. To make the drive worth it, I (note: not we, just I because Erik was not with me on this) planned to ride as many miles as we could. First, Donner Lake Rim Trail (DLRT) and Hole in the Ground (~30 miles reported to be very fun by both Patrick and Dirk) and then, Emigrant Trail (I got a 27 mile track online).  But Erik was still sound asleep. He had had a long week and needed the rest. I didn't have the heart to wake him up. So, I resorted to accepting that if we didn't get up early enough, we would just do DLRT+HitG, which by itself should be a ride that's worth the trip. But I was not willing to give up the hope that we could still do more than that, so I lay awake gauging Erik's breathing pattern. Finally, he woke up around 3am (after all, he went to bed at 8pm last night) and knew what I was up to. We got out of the door around 4am. By then, the trio had been riding in the dark at Coe for 2 hours. I went back to sleep in the next four hours when they continued to ride in the dark and Erik drove me and our two bikes up north with his WWII book playing in the speaker — everyone is where he/she was meant to be.

It was around 8:35am or so when we started riding at DLRT trailhead. (I started my GPS a bit late after we'd been riding for a while.) With the cloud coverage, it was not as cold as it could be for that altitude. Our ride started with a gradual climb, which also helped warm us up.  I had high expectations for the trail and I was not disappointed. There were great views along the way. The riding was mostly easy, but there were also challenging sections through the rocks. I was amazed by the amount of rocks that were moved for this project. The result is a challenging yet all cleanable trail — my favorite type. I didn't clean every tricky spot, but knew that they were within my ability. We just need to come back to it and maybe next time I would not be foregoing do-overs for long mileages. We pressed on steadily at a leisurely pace.

There are abundant colors on the ride.

Donner Lake Rim Trail is a masterpiece in trail building.

At 10am, we reached the Hole in the Ground (HitG) loop. I was just about to find out what this famous ride was about. But I had no way of finding out where the trio was at Henry Coe on their pursuit.  Were they as on schedule as we were — I was still quite positive that we would be able to do the 27-mile Emigrant trail ride afterward despite that we had not been pushing the pace.

The first part of HitG was a gradual climb. I reached the vista point at the top ahead of Erik, so I stopped. Two riders were already there, in resting mode as they were off their bikes. A few friendly greetings evolved into an exciting bike talk, which elevated in the level of excitement when Erik joined in. As it turned out, they were Ben and Tom from Colorado. Ben had just acquired a Santa Cruz Tallboy — to be accurate, his wife bought it and they both rode it and he fell in love. Even though he had his LT2 with him when we met him, that didn't prevent them from discussing in depth about the bike that Erik was about to purchase. Tom was riding a Lenz, which Erik also studied with great interest. I loved bike talks (I think I started it), so we all stayed put at the Vista Point. But finally I realized time was slipping away, but despite my multiple nudges, I couldn't get the guys to move. Finally, I had to ride away saying that I was giving myself a head start. I think that finally worked. Since now we were riding in the same direction at about the same pace, there were many stops where the guys talked. Ben was obviously the most skillful of all. It was amazing to watch him playing on the rocks while riding along effortlessly. For the short period of time when I followed him, I thought I would just follow his line. But I changed my mind quickly after I found out that he would divert from the beaten path and always playfully hopped on or off the rocks on the side of the trails.  Most of the time, I wasn't able to follow him anyway.

When Erik was just riding with me, he wasn't too motivated to go fast, up hill or downhill. He was feeling all kinds of ailments due to previous injuries, lack of riding in general, and a bike too small for his size, etc.  So I was glad to see him raise his pace when flying downhill with Ben. They would just reach a re-group point and start talking bikes again. But we had to say goodbye with Ben and Tom when they pressed on for their afternoon engagement and we chose to make a short out and back to the Lower Lola Lake. But of course by then, we had spent so much time chatting off bike that I knew we would not be able to complete the 27-mile Emigrant Trail ride in light. We would just play it by ear then. The newly forged friendship was totally worth it though.

Guys can talk and so can I!

A short break by Lower Lola Lake

When we popped out on the fireroad, I was puzzled — so far, HitG has been all ride-able. Where are those big steps that even Patrick had an over-the-bar (OTB) moment and Jeanne had walked (note: both are very skillful riders)??? But that question was answered very soon when we turned on to Lola Montez Trail. First, the steps were not very big and generously spaced, but soon they became bigger and bigger and closer to each other too. I kept thinking I would go OTB sooner or later, yet my FTM kept rolling down one after another. I was too scared to bail so I just let the bike take me along the wild ride. But finally, I got to a sharp right hand hair pin and my bike was headed down a drop that seemed like a cliff. That was it, I put my foot down. Just then, I found that my heart was pounding — the adrenalin was rushing through my body like crazy.  It took me a while to slow down my breathing. By then Erik had been long gone — he only had one dab at that turn.  With the steps closely packed, I walked down a few steps before getting on the bike and riding the rest.  That, finally, was the end of HitG. The rest was just riding on pavement and fireroad to close the loop before we got back on DLRT for the return leg, which we finished at around 3pm.  The trio should be nearing the end of their big Coe ride by then too.

I knew that Erik would be happy to call it a day then. But I convinced him the next ride would be easy. It would just be a relaxed ride. After we got some water in town and ate our lunch, we went to the trailhead for our ride on Emigrant Trail. As I found out, Emigrant Trail consists of many segments. The directions I found online put us at the trailhead for the segment that leads to Stampede Reservoir. The trail was indeed easy despite some ups and downs. In Erik's words, there was too much climbing, but he kept up the pace and did not lag behind.  The reservoir was low, but still a beautiful spot. When we returned to the car, I asked him if he was sure he didn't want to do the segment to the other direction, and he was sure. That's okay, we would be night riding if we continued (for which I did prepare lights), but I was happy with what we did and had fun.

This segment of Emigrant Trail is very relaxing.

Tampede Reservoir

This part would be under water after rains.

When we changed and put the bikes away, it went dark. We were done with our ride, but what about that trio? Did they ride into the dark? Did they finish all 100 miles? Were they all safe? Those questions were answered when we got home at midnight and I saw Patrick's report on Plus3.  They fell behind schedule and "only" did 80 miles (15k' of climbing). Slackers! Compared to theirs, here are our two "gigantic" rides at Tahoe:

Here is our photo album.

I rode to the site with Patrick and Roy. Worked mostly with a Pulaski, but also spent some time sawing. Took a ride out in the truck so I could return the volunteer placard only to find out that Paul and Chris were going back straight to Gilroy Hot Springs. I'm keeping the card for now, which means I should try to return for another trailwork soon.

I had a good time, but was feeling a bit tired afterward. Erik and I went to Korean Tofu House in Cupertino for dinner. We finished everything on the table!

Many photos and some stories are in this MTBR Thread: http://forums.mtbr.com/showthread.php?t=657119

A few days ago after our last weekend's ride, Skyline35/Charlie brought up this Everything Skeggs (aka All of Skeggs) ride, conceived by Biking Brazilian. I tried, but couldn't get the idea out of my mind even though that meant I had to say to Erik that I would not go diving with him and his friend, a plan they made a while back. However, when I tried to recruit riding partners, the friends I asked all gave legit reasons not to do this ride, or not to do this ride with me on this day. (And ratpick/Patrick beat me to it by three days.) Fine, I'll with just ride with me and myself then!

I started the ride at a crack 'o dawn 9:27am. Okay, "crack 'o dawn" was the plan and 9:27am was reality. That's okay, riding solo, I'd like to wait for the mountain lions to have been fed before I get on the trails. The rest of the ride all followed the plans perfectly though. The plans are:

• Do not crash.
• Do not have major mechanical issues. Flats are always a time sink.
• Do not cramp.
• Do not bonk.
• Do not get lost.

I did have one moment of scare though. That was when I was flying down ECdM trail with only about three miles to go near the end of the ride. I turned around a corner and suddenly saw a rider coming up. I braked hard and the almost bare rear tire skidded a little. Then I wanted to pull over to the side to let him by. That was when I still had a little speed and a root that stuck out of the wall on the side that I didn't notice clipped my handle bar. My bike twitched and started tipping towards the cliff side. I can't count how many times I had tipped over because I couldn't clip out, but luckily this was not one of them. I managed to got my feet on the ground before the bike went over the cliff. Whew! I immediately did a head check -- I had been riding very conservatively the whole ride and I would not screw up in the end!

I could feel my thighs threatening to seize up from time and time and I was always able to back off just in time to prevent it from cramping up. I made sure to keep drinking my sports drinks and ate quite a bit during my breaks. I did not get that noodly legs feeling throughout the ride. Whoohoo!

Not getting lost. Well, I know the place well enough not to get lost. But what I really needed was to follow the route religiously so I would not leave any segments out because that would have not been All of Skeggs. I did over shoot Timberview on its out and back (went about 0.15 miles too far before turning around). That turned the GPS (Garmin Edge 305) "Do Course" feature useless (a bug in the software), and that was only 5 miles into the ride. However, instead of reading the directions at every intersection, I was able to keep moving most of the time. Here is my secret (click to see the full size):

As you can see, I broke the route into a few fairly simple segments. Every time I just needed to remember the segment I was doing. It worked pretty well for me because otherwise my stop time would have been more, but instead my over all time was less than seven hours.

I was amazed how well thought out this route was. It tackles the most difficult climb (Lower Fir) and the most challenging trail (S. Leaf) in the early stage of the ride. The more into the ride, assuming the more tired you are, the less technical the riding gets. Not only that, it covers all the most popular trails such as Manzanita, Steam Donkey, Blue Blossom, Resolution, and Giant Salamander in their "correct" direction. The only modification I made was I did the out and back on Spring Board Trail right after Blue Blossom before exiting CM06 so that I knew once I took a break at CM06, what was left for me (about 16 miles) would be mostly just fun downhills and easy uphills.

I ran into two friends with their respective groups on the ride. At two occasions, different riders (spartan23 and Neela from MTBR) recognized me from the MTBR posts and we had nice chats. Neela made a comment that he saw my ride last week (in this MTBR thread) that was just ridiculous. I made a mental note not to say anything about the ride I was doing. Another thing that made me happy was I was able to give directions to a few people on the ride off the top of my head. Glad to put my knowledge about Skeggs to use! It was embarrassing though when I kept running into the same groups a few times because I was doing a lot of out and backs (in the south east quarter). They must have thought I was weird.

For the last third of the ride, I had the GPS on map mode. I didn't want to know the time because I didn't want to worry about it. Figured I would just ride based on how I felt. I cheered out loud when I got back to the car and saw that my ride took less than seven hours. That was a whole hour shorter than I had expected. Yeee ha!

Now, this ride had officially made my Skeggs Ride Collection. For details of the ride (directions and map), please see that page.
