500 Thailand

Registration transfer or participant detail changes are permitted until 30 September 2026, or until the event reaches full capacity, whichever occurs first. A service fee of 500 THB applies per request. No changes or transfers will be accepted after this date.

Mandatory gear is checked on bib collection day and includes a phone with a Dtac, AIS or True Move SIM, a reflective vest, a whistle, a water backpack or bottles, two emergency blankets, and basic first aid supplies.

THA 500 has 44 service points and 4 drop bags at 111 km, 199 km, 287 km and 408 km. THA 300 has 26 service points and 2 drop bags at 88 km and 209 km. THA 200 Manora has 17 service points and 1 drop bag at 111 km. THA 200 Jik Jong has 16 service points and 1 drop bag at 88 km. THA 100 Phi Lu has 9 service points and no drop bag.

Coverage is patchy in the mountains. The organisers estimate that Dtac, AIS and True Move SIM cards give roughly 70 to 80 percent coverage along the routes, which is why a phone with one of those SIMs is part of the mandatory kit.

Pack spare clothing, extra nutrition, foot care supplies, a head torch with spare batteries and anything you personally rely on between checkpoints. Drop bags are only available at the distances listed for each race, so anything you need elsewhere must be carried.
