How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 18, 2026.

Common Questions About Running a March 10K in Pennsylvania
What is a good 10K time?
Across the 4 of these March 10K races with published results from past editions, the median finisher ran 1:03:03, and the median winning time was 57:21. So anything under 1:03:03 puts you in the faster half of a typical field. That is the middle of these RunSignup fields, walkers and charity entrants included, not a national average.
How big is a typical March 10K field?
The median one finished 8 runners, across the 4 of these March 10K races with published results from past editions. Most are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field, with a last recorded finisher at 1:26:43.
