Overview

Held in Dehradun, India, the Dehradun Ultra Run 50km takes runners along a 25 km out-and-back paved route that packs 1300 metres of climbing into the distance. With 26 metres of ascent per kilometre, the continuous gradient demands disciplined pacing on the asphalt.

A 9-hour time limit demands an average pace of 10.8 minutes per kilometre to finish, setting a cut-off tighter than 65% of 50k events and more generous than 35%. Runners cannot afford extended slowdowns on the climbs if they want to clear the final checkpoints.

Organised by Thrill Zone, the event drew 37 finishers in 2025, leaving it bigger than 49% of 50k fields and smaller than 50%. The entry fee is 4000 INR for runners targeting the 50 km distance.
