Overview

Held in Dholavira, India, the White Sand Ultra 100km is a fixed-distance road race organised by The Hell Race across the largely flat terrain of the Rann desert in Kutch, Gujarat. With a 16-hour time limit requiring a minimum pace of 9.6 minutes per kilometre, the cut-off is tighter than 57% of 100k events and more generous than 43%.

Runners face an out-and-back route on asphalt roads featuring both smooth and scarred sections. The 2025 edition saw 27 finishers, representing a field bigger than 40% of 100k races and smaller than 57%.
