My friend did the one in Austin and said it was HORRIBLE.
No color. No headbands. It rained the couple days before so the course was extra ridiculously dangerously muddy. Ruined shoes, messed up knees, took them 1:21 to complete the 5K... and no color. It didn't make it down from where ever it was supposed to come! (some color- but not enough for everyone)
She said no training of volunteers- just about the worst experience she has ever had at a race.
Hopefully your races won't be like that!
