Swimrun Race Organisers

Blue Sky Endurance

Blue Sky Endurance Fest logo


The Blue Sky Endurance Fest takes place in South Carolina, U.S.A., in September. It is basically one event, but offers three race distances, so it's a great opportunity to try out this new sport.

It all starts with a one-mile swim around Trophy Lake, followed by a one mile run around the lake. That makes one round, (2 miles total) and is called the 'Skinny Dip'. If you choose to do the next distance up, you just do it all again, and the middle distance is called the 'Double Dip', at 4 miles.

The longest distance ('Third Time's A Charm') adds yet one more round, for a total of 6 miles.

Have a look at our Blue Sky Endurance page for more information.
