Chilly morning but warmed up quickly. Never too hot but wasn't drinking enough early on. Only carried a 12 oz. handheld and even with 4 aid stations on the 10 mile loop got a little dehydrated. I think I did ok with nutrition, 3 boosts, 2 cliff shots, 2 gels, 1/2 PBJ, plus pretzels at aid station. Big handful of animal crackers once also. Lap 5 was the toughest but was able to recover and run most of the most of the last lap. Garmin died at 50 miles.
