Lunchtime ride. Coworker is all "let's ride at a nice easy pace today." Yeah whatever. We rode the Hayman route, so named because of a 6 meter tall guy wearing a cowboy hat and holding a pitchfork, standing at the end. http://www.roadsideamerica.com/tip/5905
The last 2.5km to this is a washboardy, twisty dirt climb with two right-angle turns. It's fun. It's also a segment on which I used to hold the record speed, and have been vaguely wanting to recapture it from the guy who took two seconds off my best time a while back. So, since we did in fact cruise at a reasonable rate up to the start, and the ground was slightly damp, and it's not broiling hot right now, I took off and blasted through it, to see how it felt. The time I set the record, I got to the end and felt destroyed: coughing uncontrollably, unable to stand. This time I pushed pretty hard -- averaged a 185 beats per minute heart rate over the four minute effort -- but at the end I waited for two minutes for everyone else to catch up, while catching my breath, and took off and led for a while. It turns out I had exactly tied my previous record, with much lower perceived effort. Total adrenaline rush.
