Oliver Turner initiated this open water swim event while a graduate student at Colorado State University. He came up with the idea of a long-distance swim that would challenge the swimmers and also be a fundraiser for the Wingshadow Foundation. In 2003 the 2.4 mile swims were added. With the first age group (1000 yard, 250 yard) swims being added in 2006 at Carter Lake. In 2007, all swims were brought back to Horsetooth and the swim name changed to the "Horsetooth Swim" and the beneficiary changed to Team Fort Collins, who was one of the beneficiaries in 2006 as well.

The 2000 Carter Lake swim occurred because of water was drained from Horsetooth to allow the dams to be repaired. The out and back swims of 2001 to 2003 occurred because of low water levels in Horsetooth. The Army Corps of Engineers lowered the water level significantly in order to repair/rebuild the 4 dams that created the reservoir. This meant the reservoir was not long enough to complete 10 km from end-to-end as in the first year. Following completion of construction, Horsetooth was allowed to refill and a continuous, 1-way, 10 km swim is back in place.
