Overview
The Sandman 50, a 50km trail race, will next be held on January 23, 2027, starting and finishing in Dunsborough, WA, Australia. This race, first run in 2018, is organised by Geo Bay Swim Pty Ltd.

With 89 finishers in its 2026 edition, this race has a field bigger than 76% of 50k races, making it a larger event among its peers. The race has been held 9 times since 2018.
