This race IS the World’s Highest!
With a start point elevation of 3500 Mts, which is higher than the max elevation of any of the Ultra Races (currently, that we could find). Most of the race route remains above 3000 Mts, only briefly descending below that altitude. The Max elevation of the 1st edition is 4100 Mts (13480 ft) and the total Elevation gain is 10350 Mts for the 600 KM RQ.
Starting in Leh, Ladakh the race route heads south briefly till Thiksey, turns around to head past Leh on NH1 headed for Srinagar. The route goes over Fotu La at 4100 mts on the way to Kargil and Dras only the return the same way.There are numerous challenges in addition to the possibility of High Altitude sickness. The region is remote with precious resources, the route has only a few tiny villages and basic amenities available. The exposure is extreme in every sense. For safety reasons, to avoid unplanned and highly unsafe halts for rest along the route, the RQ race has been designed differently from most RAAM Qualifiers. The Great Himalayan Ultra includes a mandatory 3 hour sleep break at the lowest point of the race in Kargil.
