The Simpson Desert Bike Challenge

Each September, competitors, support crew and officials gather in the Australian Simpson Desert for the annual Simpson Desert Bike Challenge.
SDBC is a 5-day MTB event covering 300km or 500km. Each race day has two stages – approximately 80km morning and a 50km afternoon stage. Riders have the option to compete solo or in a relay team.
Riders are required to bring a dedicated support crew or they have the option to join a support crew.
The course traverses some 700 sand dunes, salt lakes, vast cattle stations and gibber plains. Riders and crews will experience all the diversity of this rugged and beautiful desert.
