Bison Trail 18 2026

Bison Trail 12 is the 12 km race within the Bison Ultra-Trail series, held in Supraśl, eastern Poland. It is a UTMB Index race, but it remains a compact trail run rather than an ultra. The course features only 83 meters of elevation gain, making the challenge focused on fast running over trails instead of enduring significant climbs. The results indicate a competitive local field, with 274 finishers and Polish runners taking the top positions. The winning time was 44:51. Second and third place were separated by just 38 seconds. Age categories ranged from U18 to older masters divisions, including specific groups for men aged 55-59 and women aged 40-44.
