Mercer County Half Marathon

Mercer County Half Marathon is held on August 29, 2027, in Robbinsville, New Jersey, on a course that makes use of the area's parkland and green corridors. Start times and elevation gain are not listed in our records.

Central New Jersey at the end of August is humid, and park paths hold that moisture under the trees rather than dispersing it. Start the first three miles at a pace that feels conservative, take fluid before you want it, and remember that a half marathon run in these conditions is worth two to three minutes more than the clock shows.
