Disappointing First Race

This will be a short post since I don't have too much to say, but I wanted to post a brief recap of my first MTB race yesterday at the Feel the Burn event in Warsaw, MO.  It started off just fine with me hanging with the front of the pack without too much difficulty aside from my lack of technical skills on loose rocks, roots, etc.  Then I was hopping a typical log barrier lying on the course and my chain came off.  I got off the bike and fixed that, and several seconds later I was playing catch-up.  Not a big deal since by the end of the first lap I was back with the front group.  However, early in the second lap my tubeless system failed on my rear wheel/tire and I was stuck on the sidelines for several minutes dealing with that and installing a tube.  That ended my competitive riding for the day.  I ended up finishing the lap and riding the third lap for some extra training, but that turned out to be a mistake.  I started cramping fairly severely and frankly just felt nauseated, so I'm pretty sure my nutrition and hydration leading up to the event was below par since I drank a ton during the race.  This weekend I've got my first half-marathon on Saturday and another MTB race on Sunday, so I'll likely post again after that.  I'll be sure to chug lots of fluids throughout the week!
