Overview
Desafio Punta Negra 70 km was a trail race in San Juan, Argentina, that covered 66.6 km with 2690 meters of elevation gain. The profile packed 40.4 meters of climbing into every kilometer, making sustained mountain running the dominant factor on race day.
Despite the vertical demands, the race offered an exceptionally forgiving buffer against the clock. The 17-hour time limit demanded a pace of just 15.3 minutes per kilometer, making the cut-off more generous than 89% of 50mi peers and tighter than only 11%. That wide window left ample margin for runners to grind through the steep sections without risking early elimination.
With 66 finishers in 2025 across an event history of 3 editions, it drew a mid-sized starting line that was bigger than 61% of peer fields and smaller than 38%.
