Summit Run – Lurntsu Circuit (SRLC) is the third race in the Summit Run Series, following Indrahar and Sethan–Hamta. Set deep in the forested trails of the Tehri–Garhwal Himalayas, the race offers runners a raw, immersive mountain running experience across ridgelines, meadows, and remote high-altitude terrain.
What makes SRLC truly unique is that it is the only trail race that includes an overnight camping experience. Participants arrive a day early and stay at a forest campsite near Deolsari, creating a rare blend of trail running and mountain camping. The race is not just about race day performance, but about slowing down, acclimatising, connecting with the mountains, and sharing the trail-running spirit around a campfire before the start.
Designed for both seasoned trail runners and those stepping up to longer mountain distances, SRLC offers multiple race categories while staying rooted in the ethos of mountain endurance, community, and responsible trail running.
