Cross Camp






This one time at Cross Camp, Ali made me do funny things with my bike.






In all seriousness the Ridley Cross Clinic on Saturday was amazing. I've never gained more two wheeled knowledge in one day in my life. Ali and Kathy took control of me and the rest of the newbies from the start and lavished us with one on one attention. We went step by step through the mount and dismount until we had all perfected it and then moved on to cornering, braking and finally a simulated mass start. I caught on to the whole thing pretty quick and by the end of the day was able to hit the barriers at full speed. I signed up for Dr X's Thursday training sessions and will be able to hit most of those so I should have the technique down pat by the end of the season. Now if I could only get that top end fitness thing going.


Yes those are full size barriers, they just look like the kiddie ones.
I did say "hitting the barriers full speed"

Tire rolling resistance study

I read this very interesting study the other day on tire rolling resistance. A common idea many people have that the higher the pressure and the narrower the tire the less rolling resistance you have. While this is true on the road any time you are off road (including gravel or hardpack) the less pressure you run and the wider your tire the less rolling resistance you have. In the study they show that a 2.1" tire at 57 PSI has 50 watts more rolling resistance than a 2.4" tire at 21 PSI with the same tread pattern. The argument that the wider and thereby heavier tire slows you down is true but only by 4.2 watts per 500 grams of weight during acceleration only. Tread pattern does make a difference as expected. Low profile/semi slick tires were proven to have much less rolling resistance than tall knobby tread patterns. So wide semi slick tires run at low pressures have by far the least rolling resistance with weight making a small but measurable difference. This was kinda what I thought all along but I was very suprised to see the wider tires having less rolling resistance. I've always been a 2.0-2.1 semi slick type of guy but maybe now I'll have to look into those 29x2.3 Karmas for next season.

Spanker Crest

Steve, Rich and Ken joined me on Saturday for what I have decided will be an annual ride I've christened Spanker Crest. It was the absolute best mountain bike ride I've done hands down. I was a little nervous heading into the ride and felt like I might have some trouble keeping up with the group. Rich is an accomplished Iron Man, Steve destroyed all comers in the ICUP this year and Ken killed it in the Tour de Park City this summer. I did myself proud and by feeding well I was able to hang all day.

We met at the base of Millcreek at 9am and headed out around 9:30ish. The plan was to ride up and over Emigration to the base of the Mormon Pioneer trail, Pioneer trail over Big Mountain, down into East Canyon and over to Jeremy Ranch. Lunch stop at the Jeremy Store, cross the freeway, poach the private singletrack in Pinebrook and climb it up to Mid Mountain. Mid Mountain all the way across to Spiro, Powerline, Scotts Pass and finally Wasatch Crest trail back to Millcreek. My rough estimate for the ride was 60 miles. It ended up being 78 miles with almost 10k feet of climbing taking 10 hours start to finish.

What a sweet ride. The trails were all in perfect condition and the weather was amazing. The Pinebrook climb is lung searingly steep but the trail is buff and has very little traffic. Mid Mountain from Pinebrook to the Canyons can't be beat. Crest is in the best condition I've seen all year as were the Millcreek trails. The only negative to the whole ride was by the time we got to the top of the road at Millcreek at around 7pm the temperature had dropped to 47 degrees. I didn't have a jacket which made for an interesting descent down Millcreek.

My main goal for the ride was to feel human at the end. When I walked in the house around 7:30 Rhonda expected me to be a zombie, crawling around moaning for food as I've done many a time after big rides. Instead I was able to hang my bike up, put all my gear away and hop in the shower without a problem. During the ride I drank 128 oz's of my homemade energy drink, 64 oz of water, 4 gels, 2 bags of Cliff Shots, a bag of peanut butter pretzel's and a giant Pumpkin cookie. That's more sugar than I usually eat in an entire week but I burned every calorie of it plus some during that ride.

I'm taking reservations now for next years running of the greatest MTB ride in the Wasatch. Spanker Crest 2009.

**update** I estimated the climbing at 10k feet but according to Rich's Garmin is was actually over 13k feet.

First ride: Stans CX Tubeless

Hit the Pipeline trail last night on my recently converted to Stans Tubeless cx wheels. After mounting I felt the setup was pretty solid since the bead on my Kenda Kwick Cross tires were a byatch to pry over the rim. I can't see that tire rolling off for anything. The ride proved to me the instant value of tubeless for cross. I was very careful on the DH to avoid any large rocks but even with running 45 lbs in my tires I still pinched the rear tire into the rim multiple times. This obviously would have led to an instantly pinch flatted tube had I not been tubeless. Add in the protection from the Wheeler goatheads and I feel like this setup is the way to go.

Only a week to go till Ali's Ridley CX camp and then the season kicks off the week after that with MooseCross. It's strange. I think I'm more excited for cross than I was for MTB racing this year even though I'll probably just spend the entire CX season getting shelled by the roadies.

Reason #121 why fall rocks

40 MPH (wind aided) 1 minute max effort intervals across Wasatch make even a slow guy feel fast.

Honoring the Holiday

Holiday weekends are never holidays for me. What I think happens is that mentally I think to myself "self, you have an extra day to get things done so lets go crazy". This weekend I leveled the yard around the backyard patio I installed earlier this year, I converted my cross wheelset to Stans tubeless, got in two nice road rides, hit two BBQ's/parties and finally did this to my front side yard.

Prior to this weekend the tree was there but nothing else. I ran out of steam at 8pm last night so tonight I need to plant the plants, run drip lines and clean up the mulch but I think it turned out really nice.

The end of an evil oppressor

Finally an end to the evil overlord known as summer. I like summer as much as anybody....for about a month, than I get sick of the constant sunny and 95 deg weather. Too hot. Hopefully fall will stick around until the end of December, then I'll allow winter (and many weekends spent in St George) for January and February followed closely by a spring including March, April, May and June. That sounds about right. Make it so Number One.
