Distances for City Challenges
A city challenge gives you a choice of distances, from 5km through to a full marathon. They don't have to be completed on a specific day, the whole month when that particular city challenge is active.
So, when you're registering for the event choose your distance: 5km, 10km, half marathon (21km/13 miles), and full marathon (42km/26 miles). View available City Challenges
