My first post on the mtb portion of BF. Someone suggested to me I should race a local race. It's an end of season thing and quite a few triathletes (my sport) roadies and such take part in this one as a end of season race. 27 miles non technical, some guys do it on cross bikes. I have a dept store mt bike I bought for a winter commuter. Wasn't meant to be anything but a beater bike, it's never been off road, I've never been off road. I'm looking to simply finish in one piece if I do this, bike finishing in one piece is optional.
What do I really need to pay attention to in order to do this, not racing just going out to have fun with the guys and finish this. Distance is not an issue, my skill level and the quality of my ride are the issues.
