About Umdoni100 miler
Set along one of the South Coast’s most beautifully maintained trail networks, the Umndoni 100-Miler and 50-Miler offer a true looped ultra experience in the heart of Umdoni Park. Both events run on a purpose-built 13.4km circuit that blends flowing singletrack through indigenous coastal forest with open fairways, dune paths, beachside stretches and elevated viewing decks — all with the ocean never far from reach.
Expect a constantly changing rhythm underfoot as the route moves from shaded forest trails to open coastal sections, with stair climbs, panoramic viewpoints and fresh sea air adding to the challenge and charm of every loop.
This event is hosted in partnership with the local trail custodians, the Thirsty Thursday Trail Group. A portion of every entry goes directly back into the ongoing development and upkeep of this special trail network — so every step you take helps keep these trails world-class.
Runners will move through a diverse mix of terrain, including flowing singletrack in indigenous coastal forest, coastal and beachside running, elevated viewing decks, and short stair sections that add both challenge and variety to each loop.

Did the Umdoni 54km in 2026 AttendedThe route was great and exceptionally well marked. The start\finish area was great for spectators and allowed the runners to easily get to a well stocked aid station.
