Ultra Obscura

Ultra Obscura is an exhilarating trail running experience that challenges the mind as much as it does the body. Set amidst the rugged and breathtaking terrain of Mont Sutton, this race offers runners six distinct distances ranging from 10km to 84km, each one a test of endurance and strategic planning.
The course itself is entirely off-road, winding through challenging trails with technical sections that require intense focus and determination. Runners will be treated to stunning vistas of the Sutton Mountains as they navigate steep climbs and descents on paths less traveled. This unique format rewards not just physical prowess but also tactical decision-making, making it a race unlike any other.
With only 200 spots available for this exclusive event, Ultra Obscura promises an intimate atmosphere where every runner is supported by professional medical staff including paramedics and rescue workers throughout the course. Participants will enjoy high-quality technical shirts, pre-race meals, complimentary photos from the day's action, as well as personalized medals.
The race organizers, Sinister Sports, are committed to sustainability, ensuring that each step taken on these trails contributes positively to their maintenance and preservation through partnerships with local environmental groups like PENS (Parks Environmental Network of Sutton) and Plein Air Sutton. This commitment extends beyond the event itself, fostering a community dedicated to preserving natural beauty for future generations.
As runners complete their respective loops—scheduled for Saturday morning and afternoon for shorter distances and Sunday at 8 AM for longer ones—they will not only challenge themselves but also be part of an organized and passionate race that celebrates both athletic achievement and environmental stewardship.
