Lucifer's Crossing takes place Sunday, May 31, 2026, at the Old Y Camp in Robert Treman State Park, Ithaca, NY. Distances offered are:
- Half Marathon: 13.2 miles
- 10K: ~6.66 miles
- 5K: 3.3 miles
Registration opens in October. Entrants receive park admission, an event T-shirt (only guaranteed for registrations before May 1), and post-race food. Early packet pickup is available on the Friday before the race and race-day check-in is at the Y Camp staging area. The event has a course cut-off.
Course and logistics
All distances begin with a roughly 1.5 to 2 mile rolling ascent on the wooded Rim Trail and include a historic steep stone staircase. From the top, 5K runners turn left to return on the singletrack Finger Lakes Trail. 10K and half marathon runners descend through the Lucifer Falls gorge, ascend the Red Pine Trail, pass the historic Old Mill, and finish with a mostly downhill section on the Finger Lakes Trail singletrack. Half marathon participants complete two loops of the 10K course; the 5K follows an abbreviated opening loop. Parking is along the access road off Route 13 South, about 0.5 mile from the split with Route 34, with the Y Camp area serving as check-in and start/finish.
