This swim is a 2-loop course from the South Bay swim beach. The course starts on the beach, goes 0.6 miles out, where swimmers will turn around a buoy and return, swimming around another buoy, then back out around the buoy and back in finishing out of the water, on the beach.

There are 2 divisions:  Wet suit and non-wet suit.  You’ll indicate which you want to participate in during the registration process.

All WOWSA rules apply including swimsuit definitions. Exceptions and clarifications include:

Unlike many open water events, the Team Fort Collins Horsetooth Swim allows no drafting except where unavoidable at the start. If flagrant drafting is observed, that swimmer will be disqualified.

WOWSA Marathon and  Channel Rules state swimsuits shall not go beyond the end of the groin or shoulders.  The Team Fort Collins Horsetooth Swim allows the swimsuit to extend to the knees.  Any swimsuit that does not meet these requirements will be classified as a wet suit swimmer.


First, second and third place, male and female, will receive a medal in each category (wet suit and non-wet suit).
