clarks tt cx

I have been meaning to get down to Draper and ride the clarks TT on the cross bike for a while. Tanner told me it was in a good shape and prime for CXing. This afternoon I had to ride out to Sandy anyway so I just kept going down to Corner Canyon. The recent moisture has really helped the trails down there and they were all fun even on the CX bike.

I rode up to the bridge, took my LS jersey off and stashed it in the bushes, put some gloves on, and hurried to start so I would not run into the traffic I passed on the way up. Because I don't have a watch or HR monitor with a functioning battery, my new/old cell phone does not have a stop watch, and I don't have a computer on my cross bike I had to rob the one off my road bike and stash it in my Jersey pocket. Worked well other than the futzing around to get it out.

I started slow compared to what you would expect for a TT, just a steady fast tempo for the first few minutes. Because the grade is mellower at the bottom you can't gain much time by starting to fast and you can sure lose some. I never let my legs load up and just slowly let the terrain up the pace for me. Everything went well except about 3/4 of the way up I had that unmistakable feeling that I need to use the restroom, yup #2. Ohran always says that's a good sign of form when you need to poo while on a ride. Anyway, I made it to the top without incident but hit the John as soon as I got back to the parking lot.

My time was 8:24. I knew I was going faster than the last time I did it but unfortunately it's not because I am stronger. Gearing a 34 up front and a 12-27 rear cassette. I used 3 and 4 down for most of it and may have got into the 2 on the steepest part.

Why it was faster:
-The cross bike is better for standing up and pushing a big gear, in a short TT you don't need to spin like I did before. The cross bike is also a little lighter, although I was on my B bike with heavier wheels and tires. I should bust out the carbon tubulars. A rigid MTB single speed set up super light would also be really fast or even better would be a 16.5lb Cannondale Flash. Maybe next spring I will try it on a Flash! A little bigger volume tire would be better, I was worried about pinching in a couple high speed rough sections in the middle and actually had to slow down.

-Negative split pacing is faster. Look at the world record run times, negative split pacing probably accounts for 75% of all the world records, maybe more. Marathon, 10,000 meter, 5K does not matter. Faster in the 2nd half is faster overall. Last time I went out to hard and the legs loaded up early. This time I cruised into it and was never hurting all that bad, I could have gone harder for sure.

-Good dirt, not sticky but not dusty. Smooth with no horse marks, this is critical for the cross bike. When I did it before in June it was rougher and dusty. The MTB may have been as good at that time.

-Cool temps, maybe even a little to cool. My legs got that cold stiff feeling in the shade but it surely is faster than burning energy cooling the engine like in summer months.

It's to bad I live so far away because I would like to do it more often, it's a fun gauge and for a guy that does not do intervals it is a good way to get some intensity in without burning up the CNS.

The ride back on the road was nice and made for about a 3hr ride with a 8 minute effort in the middle.

Nice work. I live at the top of Suncrest and ride Clarks on just about every mtb ride I do (it's the way home). I can't imagine going that fast.

I rode it the other day on my SS cross bike (36 x 16). I wish I would have timed it.

Likely a little to much gear for me.

I tried yesterday on my mtb, had a great, fun 45 min warm up, went to hard and blew up at 4.5 minutes in. Then I gave up, your post depresses me, I am going surfing.

Nice work, Bart. Good lessons with the negative split. I'm always hurting way bad in the second half and just hanging on.

Bart I saw you over there yesterday. I was the guy on the Niner in the Masher jersey. Had I known you just laid down a time like that I would have handed over all the treats I had in my back pocket. That's an unbelievable time!

Interesting strategy on the TT. I have done it both ways. Recently I tried blitzing it from the bottom and I ended up with nearly an Identical time as when I ease into it. And it hurts less. I gotta go back and try it again this week.

Years ago the DV NORBA national started with a prologue up the bobsled. About a 6 minute climb with the steep stuff more towards the top. Possibly the most painfull duration ever, to long to sprint but to short for any thought of being aerobic.

Most people take off in a dead sprint to get up to speed and then just hang on to the top after blowing up, me inculded. I remember watching Carl Swenson take off at a mellow pace and then later seeing he was way up on the leader board. This was the year after he retired and was just doing a few races for fun. The weekend before I had beat him pretty good at the DV Icup so our fitness was likely similar. He killed it and I have never forgot his negative split pacing stratgey.
