8-mile trail race at Lincoln Mountain.
I approached this less as a real race (where I'd be making an effort to push my pace), and more as just a fun, supported training run with hills (my goal this summer is to get stronger on hills). I was able to get up the sucky southern hill without walking -- even passed a few people there.
It was a very small but fun race (most people did the 4-mile option). My finish stats were 16 / 25 overall, 5 / 12 female, and 1 / 3 age group (but they only gave out overall awards).
Excellent free beer, quesadillas, and five-minute chair massage afterwards.
I showered at the rec center in Castle Rock and then added probably another mile of meandering around at the outlet mall. :-P
