Featured: Gorge Waterfalls (Cascade Locks, OR)

Gorge Waterfalls 100k and 50k ultramarathons return to Cascade Locks, Oregon, April 11-12. One of the most scenic courses in the Pacific Northwest, Gorge Waterfalls takes runners on a tour of the Columbia River Gorge National Scenic Area, passing waterfalls such as Wahkeena Falls and Multnomah Falls, the most photographed waterfall in the United States.

Both races annually attract competitive fields who will compete on a mix of technical, rocky terrain, smooth singletrack and short sections of paved path. The 100k sets off on Saturday and follows an out-and-back course with around 11,000 feet of elevation gain and loss. The 50k starts Sunday at Wahkeena Day Use Area and heads back toward the finish at Marine Park.

Live on-course tracking can be found on the official race website.

Featured: Forget the PR Mohican 50k (Loudonville, OH)

The 16th running of the Forget the PR Mohican 50k kicks off Saturday at Mohican State Park in Loudonville, Ohio. The classic spring race annually attracts a strong group of Midwest ultrarunners for its old school vibe, supportive volunteers, social post race gathering and scenic trails.

On course, participants will have 10 hours to navigate a challenging loop through the park’s wooded ridgelines, steep hollows and rolling terrain. The race gets its name from the constantly changing conditions, with plenty of roots, rocks, sharp climbs, more than 4,800 feet of elevation gain, river crossings and the potential for early season mud.

All finishers receive a custom Forget the PR Mohican 50k buckle. Read more about the race here.

Known as one of the fastest trail courses in Texas, Brazos Bend features a famously flat multi-loop layout with smooth dirt trails, crushed gravel paths and strong aid station support, making it an ideal setting for chasing PRs or tackling your first ultramarathon.

Beyond the fast course, Brazos Bend is also known for its abundance of wildlife in the park’s wetland areas, including bobcats, foxes, deer, multiple species of reptiles and nearly 300 types of birds, plus the most well known trail companion, the American alligator.

Diez Vista 50k returns to Port Moody, British Columbia for its 28th edition.

The race features an out-and-back course that starts and finishes at Sasamat Lake in Belcarra Regional Park. From there, runners navigate lush West Coast rainforest single-track around Buntzen Lake and along the Diez Vista trails, encountering rocky and rooty terrain, steep climbs and descents and more than 6,500 feet of elevation gain and loss.
