The half marathon completes a loop twice with lap splits recorded. Aid stations are provided on course, with stations noted around 1.5-2 miles and additional stations for the 10k and half marathon. Professional chip timing is provided with instant results and timed splits. Race entry includes a soft-spun T-shirt (shirts guaranteed for registrations by June 15), a custom bib, a neck buff, and free downloadable finish-line photos and video. Half marathon finishers receive a finisher medal; age-group medals are awarded for top three in standard age brackets for 5k, 10k and half.
