About the race
Green Lakes Endurance Runs marks twenty years of GLER at Tulip Hill Picnic Area in Green Lakes State Park, Fayetteville, New York. The event is organized by Ultrarunning Matters and features multiple fixed-distance races plus a timed event.
The trail course includes a mix of well maintained single and double track, grassy single track, dirt roads and some asphalt. Overall the route is described as relatively runnable for a trail course, with two ascents and one long descent through upland forest where roots, ruts, and stones can be present.
The upper meadows, called the Serengeti, provide more than three miles of open running per loop. The lower lake section runs close to the water, is shaded, has a few roots, and is generally flat. Directional and confidence markers appear every 100 to 200 meters.
Distances and formats:
- 100K - eight course laps of about eight miles each
- 50K - four course laps of about eight miles each
- 25K - two course laps of about eight miles each
- GLER GALEFORCE 12 Hour - repeated clockwise three mile loop around Green and Round Lakes
Amenities include t shirts for entries made at least 14 days prior, finisher medals and choice of a coffee cup or pint glass, stocked aid stations plus an unmanned water drop, podium and age group recognition, a raffle ticket with registration, and space for personal bags and small canopies at the main aid station. No refunds will be accepted after July 16, 2027 and there are no deferrals to the 2028 season. Awards and schwag are distributed on race day only.
