Lucifer's Crossing, held on May 31, 2026, in scenic Ithaca, NY, offers a uniquely challenging and rewarding trail running experience within Robert H. Treman State Park. With distances including a Half Marathon (13.2 miles), a distinctive 6.66 Miler, and a 5K (3.3 miles), this Red Newt Racing event is renowned for its "difficult course with scenery" and "6.66 Miles of Trail Gluttony" motto.

Runners will embark on an "absolutely beautiful course" that features some of the region's finest flowing trails and breathtaking landscapes. Each distance begins with a rolling ascent of the wooded Rim Trail, leading to a historic and steep stone staircase. The 10K and Half Marathon routes then descend into the majestic amphitheater of Lucifer Falls gorge, followed by a steep climb on the Red Pine Trail, a pass by the historic Old Mill, and a fast, mostly downhill stretch of the Finger Lakes Trail Singletrack. Half Marathon participants complete two loops of the 10K course. Expect varied terrain, including potential muddy sections, creek crossings, and "quad-busting stairs". Typical race day conditions in late May offer pleasant highs around 72°F and lows near 49°F, with a mere 15% chance of precipitation.

The race culminates with a fast, lush singletrack descent, opening up to a paved road for the final 600 meters towards the finish line at the Old Y Camp staging area, where spectators gather to cheer. Runners consistently praise the "challenging and fun course" and the positive atmosphere. Post-race, enjoy delicious food from Fittnell Farms, making Lucifer's Crossing a truly memorable event that combines intense trail running with inspiring natural beauty.
