MORE than 1400 athletes are expected to compete in one of the world's biggest adventure races when they compete in the Anaconda Adventure Race on Geographe Bay in Dunsborough on November 2.

The 52km race will start at 7:30am at Old Dunsborough Boat Ramp and include ocean swimming (1.8km), ocean kayaking (12.5km), coastal and trail running (14.2km), mountain biking (22km) and a final run (1.8km).
