I am the team anchor, not so much because I am the go-to-guy anchoring the team but more because I outweigh the other three guys by a sizable amount!  I have been riding mountain bikes in Moab since 1984 and have done two 24 hours of Moab in this class.   I am never fast and demonstrate no finesse at all but I have a good time riding with all these other riders on this great course.   I function as team mechanic so I make up for being slow by keeping everyone else's bike running smoothly.
