Mobius

Mobius is a certified marathon (26.2 miles) held at Falls Township Community Park in Levittown, Pennsylvania, on November 15, 2026, starting at 7:00 a.m. The field is capped at 200 participants, and the course is a flat, multi-lap loop, USATF-certified and eligible as a Boston qualifier.

Everything about that setup points at one use: a fast time. A flat loop with a small field means no crowding, predictable splits and easy access to your own fuel each lap, which is why runners chasing a BQ often prefer this format to a big-city race. Come with a 16-week build behind you, a long run that has reached 20 miles, and a pace you have rehearsed in training rather than one you hope for. Lapped courses reward runners who can hold an even effort and ignore the scenery.
