The course of the 2015 World Duathlon Championships is a lightly undulating trip round the streets of Adelaide. To complete the full race distance, put FulGaz in lap mode and complete four laps. Running off the bike is optional! Loops are rides where the start and finish are at the same point, this lets you do multiple laps without getting weird distances in Strava etc. To ride multiple laps of a ride non-stop, go to Settings then select Laps from the Ride Modes menu.
