OTT Winter Ultras

OTT Winter Ultras returns on January 30, 2027, with two challenging distances: the 75-mile and 100-mile routes. This brutal winter ultra is set against the harsh backdrop of the Brecon Beacons, known for its rugged mountain terrain and iconic peaks.
The race begins at Penderyn Square in Merthyr Tydfil at 6:00 AM, with participants facing long hours under the dark skies as they navigate through cold, exposed trails. The event is designed specifically for experienced ultra runners who are ready to push their limits in some of Britain's most demanding winter conditions.
With a strict cut-off time of 40 hours—meaning all racers must finish by 10:00 PM on January 31—the race tests not only physical endurance but also mental fortitude. Participants will encounter steep ascents, technical descents, and unpredictable weather that can change rapidly throughout the day.
The £185 entry fee for the 75-mile route and £250 for the 100-mile option reflects the unique challenges of this event. As runners traverse through remote sections of Wales' stunning national park, they will experience a true winter wilderness adventure, far removed from the comforts of everyday life.
For those who embrace adversity and thrive in extreme conditions, OTT Winter Ultras offers an unforgettable challenge that pushes the boundaries of what is possible on foot during one of nature's harshest seasons.
