Semi Marathon du Big Turkey

Big Turkey Half Marathon is held in Clark, New Jersey, inside Oak Ridge Park, on Thursday, November 26, 2026. Two distances share the morning: a half marathon (13.1 miles) and a 5K (3.1 miles), both routed within the public park. Start times are not listed, so check the schedule with the organizer before you travel.

Running 13.1 miles on Thanksgiving asks for real preparation, so treat this as the goal race at the end of a 12- to 16-week block, with a long run building toward 10 or 11 miles and one tempo session per week. A park setting usually means a contained, repeated route, which suits even pacing and makes it easy for supporters to see you more than once. The 5K covers everyone else in the group, from walkers to kids to runners resting between longer efforts, and both fields are finished in time for the rest of the day.
