I did some local mountain bike racing last year and took 2nd in my age group overall (sport). I only did 3 out of the 7 races and had the following results:
2nd (out of 2)
2nd (out of 8)
4th (out of 5)

Will I be a sandbagger if I don't move up to expert? I don't think I'm ready to double my race miles, but at the same time I don't want to be hated among fellow racers for not upgrading! What do you think?
