Get ready to experience far more than just a race. <\/em><\/strong><\/p>\n

 <\/p>\n

The Ultra Obscura<\/strong>, organized by Sinister Sports<\/a>, is a one-of-a-kind trail running event set in the heart of the technical trails of the Parc d\u2019Environnement Naturel de Sutton<\/a>, Mont SUTTON, and Plein Air Sutton<\/a>.<\/p>\n

 <\/p>\n

Here, it\u2019s not just about distance, it\u2019s about strategy. Each participant moves at their own pace on a fully trail-based loop course, with no asphalt sections, where every decision along the way can change everything.<\/p>\n

A unique and evolving format<\/span><\/strong><\/h5>\n

 <\/p>\n

Ultra Obscura<\/strong> features a distinctive concept: a course divided into multiple loops of increasing difficulty. After each section, runners can choose to continue or stop, redefining their challenge in real time.<\/p>\n

 <\/p>\n

With distances ranging from 10 km to 84 km (solo or relay)<\/strong>, the event is designed for both runners taking on their first challenge and seasoned athletes ready to push their limits.<\/p>\n

A demanding, pure trail experience<\/span><\/strong><\/h5>\n

 <\/p>\n

The trails of the Massif des monts Sutton<\/strong> offer a spectacular and technical playground: sustained climbs, fast descents, and winding sections through dense forests and breathtaking mountain landscapes.<\/p>\n

 <\/p>\n

With significant elevation gain on longer distances and iconic segments passing by several lakes and summits, each loop represents a true physical and mental challenge.<\/p>\n

 <\/p>\n

More than a traditional ultratrail, Ultra Obscura<\/strong> emphasizes effort management, strategy, and mental resilience. Every decision, every transition, and every climb becomes an opportunity to push yourself further.<\/p>\n
