December Half Marathon

Run a half marathon this month.

December 1, 2017 — December 31, 2017
Race a half marathon whenever and wherever you like in December to complete this Challenge. Skip the registration fees and pre-dawn wake-up. Don't skip the chance to push yourself and set a new HM PR. Just pick a safe stretch of road (or trail), choose a route that is at least 13.1 miles long, and let it rip.
