This race is always a wonderful time. Even when the weather makes it brutal, the race is always super competitive, and most importantly, fun. The extra-curricular activities make it truly a great time...

The whole experience was top notch start to finish. Pre-race communication and info was great. Everything on race morning was clear and easy to follow. The announcer and music was fun and lively. The course was well marked and there were ample opportunities to get stuff at the aid stations.
