Finishline 234 Crescent Rd, Greenbelt MD 20770
Three-loop course through Greenbelt, Maryland and the U.S.D.A. Beltsville Agricultural Research Center. USATF-certified, Boston Marathon qualifier.
Relay option: Three (or two) runners:-
- Leg #1 – 9.7 Miles
- Leg #2 – 7.3 Miles
- Leg #3 – 9.2 Miles.
- Is there a “half marathon” option? No. Two runners can share the three legs any way they choose, but we don’t offer a “2 x 13.1-mile” relay option; the course is not conducive to that.
Aid stations: 13 aid stations at approximately two-mile intervals.
Comfort Stations: facilities available at aid stations (except for first one at 1.5-mile).
