Decided to give Mountain Bike racing another shot, after a few races I did back in like 1993 in my early biking days. There’s a Wednesday evening Spring series out at Prairie City OHV park just a bit outside of Sacramento. It’s very casual, and the course changes each week. Didn’t know if I belonged in the Beginners or the Sport category, but I guess after winning 2 races in a row in Beginners, I’m probably going to have to bump up soon! It’s a ton ‘o fun, fast and sketchy, with a wide range of skills out there all at once on the course - they even have a fairly well attended 10-14 yr/old category! Makes for an obstacle course of people and bikes.
Update: After winning my first 2 races, more competition joined the startline, and I ended up in 3rd for my next 2 races, but then won my 5th race.
