Warm start, warming through the race

A warm 73°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Temperatures rising to 83°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 80% is worth noting for effort level, especially in later miles.

Race Info

The Back Your Badge Half Marathon is a USATF-certified 13.1-mile course that starts and finishes at the Richard A. Carlucci Recreation and Aquatic Center in Plainfield, Indiana. Runners head west through county and neighborhood roads, then spend about two miles on Historic US 40 through downtown Plainfield before crossing an iron bridge in Franklin Park onto the tree-lined Vandalia Trail. After leaving the marathon course near Plainfield Middle School, half marathoners loop back past Friendship Gardens Park and return along the shaded trail to the finish. The terrain is mostly flat with some rolling hills.
