Unique lines

I competed in the SCCA RallyCross National Championships on October 10 and 11 with my Volvo wagon. I feel that I accomplished my goal of showing that the largest and possibly most under powered car at the event can be quite fast if driven properly. After two days of racing and 14 runs, I wound up second in the stock rear wheel drive class by a mere 5 seconds. Next time I will have the proper tires!

At the end of the fastest section from both days, much to my liking, I found a sideways braking double apex festival of speed.

The highlight of last weekend was working on the Lyons Bike Park pump track with Lee and Farid. We added a small roller to a dead spot between one of the berms and the tallest roller on the track. One very quickly gains quite a bit of altitude from a well timed manual from the small to the large roller, as well as a lot of speed. The dirt was obtained by transforming one of the straightaways into what Lee rightly calls "3-dimensional love adventure." A good pump track seriously makes you feel like a fighter jet or a Formula 1 car (or anything else that is awesome and pulls a lot of G's, for that matter). Seriously.

I'd hoped to race on that track today, but the weather unfortunately had other plans. Maybe next weekend. On the plus side, I was able to spend more time hanging out with friends and watching other people suffer at the cyclocross race at Boulder Reservoir. The night was capped off by team competitions in "corn hole" and blindfolded-inner-tube-replacement, put on by Mafia Racing and PBR. Appearently, Lindsey and I are not as good as people from Wisconsin in the former case, and Garmin-Slipstream team mechanics in the latter. Can't win 'em all.... At least it was great fun and I got some sweet PRB bike socks and cool stickers. Yeah!

100 Laps of Pump.

I did my first 100 laps on the pump track at the Lyons Bike Park today.

Procedure (adapted from leelikesbikes.com):
Ride 10 laps and take time split.
Rest until heart rate drops below 145.
Switch directions and repeat until 10 sets have been completed.
The last two sets were each 10 figures eight.

Bike Setup, track condition:
Blue Steel, fork locked out with light threshold, flat pedals.
Well worn Maxxis Ardent 2.25 @ 35psi front, Maxxis High Roller 2.35 @ 45psi rear.
Moderate bumps in north berms, ruts between one pair of rollers, dry after recent rain fall, slightly loose surface.

Summary:
Total time: 31:58.2
Ave. HR: 172bpm
Max. HR: 189bpm
Calories burned: 525
I took about 50 seconds of rest between sets.
3-4 miles distance, 1300 bumps and berms.

Splits:
2:43.2 CCW
2:47.5 CW
3:19.4 CCW
2:55.9 CW
3:15.2 CCW
3:14.7 CW
3:06.9 CCW
3:12.8 CW
3:47.8 (figure eight)
3:35.1 (figure eight)

Conclusion:
This is soooooooo much better than doing intervals on a hill or the road. I'd like work on pace and get more consistent times. My rest periods didn't seem to get any longer toward the end of the session, though concentration became more difficult.

I was so pumped afterward that I rode up one of the agro lines on the Rock Pyramid without pedaling. I also spent some time hitting the jumps on both Blue Steel and Peppermint Swirl, my 16" bike. I've done better with the table tops in the past, though I have gotten much better at the first step up. Super fun day.
