I posted about it a little in the diet/fitness thread, but will add it here since this is a more appropriate place.
About 3 weeks ago I did my first ever bike race. It was a XC mountain bike race. The course was 18 miles and 2,500 feet of elevation gain. I was in 40-49 CAT3 (the slowest category) and my only goals were to complete the race and not be last. The week prior I had pulled my right quadricep playing slow pitch softball of all things, but decided that since I was already registered I would race. Probably not the wisest decision, but there was a level of excitement about doing something like this.
I told myself going in I would just ride my own race, and maintain a slow and steady pace. That all went out the window when everyone around me shot out of the starting line super fast. My heart rate shot through the roof, and I never recovered. Normally when I mountain bike with friends we stop at the top of the hill to catch our breath, drink some water and enjoy the scenery. This was all about maintaining forward movement. The only time I stopped was when a fellow rider looked to be in a lot of pain, and said he was cramping up and out of water. I gave him about half the water in my camelback and continued on. He crossed the finish line after me, so I was happy he made it.
In the end I finished 57/81. It took me about two and a half hours, and my average heart rate over that span was 167..... peaking at 186. My heart felt like it was going to pound out of my chest the whole time, but it was still a lot of fun and a good experience. I may sign up for another race in April and hopefully do some actual training beforehand. A year and a half ago I was asking for advice on a bike purchase, and completely out of shape. I wouldn't have physically been able to even walk this course, much less bike it, so I'm proud of how far I've come with my fitness
