Wow, talk about a blast. In all the years I have ridden trails and such, I have never had the opportunity to ride an MX track because I figured it would beat the crap out of me. Yesterday though, I went and road a local track that is kept in pristine condition due to it being part of the fall series for this region. I talked myself into believing I could jump everything out there and I could do it instead of talking myself out of it. I ended up riding it for quite a while and had a blast. I can clear everything on the track minus two doubles one prior to the table top and one just after, I can't see the landing area of them and it's a decent drop so it made me nervous. Other than that, I was in heaven but now I see what you guys say about arm pump. I couldn't grip the bars for more than 3 laps at a time. Unfortunately though, it is so fun that I don't know if I can stop now.
