A Dam Good Swim

Dive in to the largest lake in the Black Hills of South Dakota for a beautiful and invigorating open-water swim race with multiple distances for all open water swimmers.

Pure Pactola offers FOUR distance options: 0.5 miles, 1.2 miles, 2.4 miles, and a 5K for you sharks out there. This will give everyone a chance to put their skills to the test in Pactola Reservoir’s deep, clear, and often crisp waters.

For our guppies in training or those who just want to see if they can open water swim, we have a 100 meter or maybe 200ish meter swim. Distance will be determined based on entries from our under 14 year old age groups (we will pretend your are 14 even if you aren’t but you will not get a prize and yes you will have to pay full price (because you have a job (hopefully.)

A Good Swim for a Good Cause

Pure Pactola is hosted and run entirely by local volunteers with a love for open water swimming, a desire for people to be active, a love of the Black Hills, & hopes for more young people to join in. A portion of each years proceeds from the event are donated to local first responders who assist in Pactola-area emergencies.

Help us support the amazing volunteer first responders, who are keeping our open waters safe.
