Run 1:

Run 1 is an anti-clockwise loop of the playing pitches area of the 15 Acres following the tarmac track; the route is flat. All traffic cones must be kept to your left. There will be lots of marshals present and anyone found cutting corners will be disqualified.

You must enter and exit transition by the official entry and exit points. We have a neutralised transition and places are not allocated. All boxes and bags will be removed from transition before the race. The usual TI rules on nudity will be observed and applied. You must put your helmet on before touching your bike.

Following a neutralised transition, the bike course will take athletes in an anticlockwise direction on a 4km route down the Acres Road, along Military Road and through the famous S-bends and finally up the Kyber Pass.

Run 2:

After the cycle its back to transition and out on the second run (2.5km) which will take competitors around the playing pitches once again before the finish line beside transition.
