Swim Serpentine routes

THE COURSES

Half-Mile Swim: This is a half lap of the Serpentine. Perfect for those after a fast and furious race, as well as those looking for a shorter, more manageable (but still tough!) swim.

One-Mile Swim: The classic distance. This is easily the most popular race of the festival, consisting of one lap around the lake.

Two-Mile Swim: A more challenging swim for those who want one, this is two laps around the lake. Aimed at those with previous One Mile swim expereince who want to really test themselves.
