Overview

With 3164 meters of elevation gain across 50 kilometers, the Merumatta Coast Trail in Lombok, Indonesia, packs an unrelenting 63.3 meters of ascent into every kilometer. Run in January, the route demands heavy mountain climbing from start to finish, yet pairs that vertical load with an exceptionally forgiving clock.

A 15-hour time limit allows a cutoff pace of 18 minutes per kilometer, making the cutoff more generous than 92% of 50k peers and tighter than only 8%. That generous margin gives runners breathing room to manage the steep gradients without chasing aggressive splits.

First held in 2024 and reaching 101 finishers in 2026, the event features a field size bigger than 79% of comparable 50k races and smaller than 21%.
