About the Event

The Tulsa Area Triathletes Open Water Swim makes its debut on Tuesday, May 26th in Sand Springs, Oklahoma, marking the start of a series of open water swims that continue through August. Nestled along Keystone Lake Shelter 2 at the intersection of South Highway 151 and Central Avenue, this inaugural event offers members an opportunity to dive into the crisp waters of Keystone Lake under a setting sun.
As daylight begins to fade on these late spring evenings, Sand Springs transforms with a quiet hum as the community gathers around the lake. The evening air carries hints of the nearby prairie grasslands, mingling with whispers of water and distant sounds of nature. For those who dare to venture out into open waters for the first time, there's an underlying sense of camaraderie that permeates through each stroke taken under the watchful eyes of volunteer kayakers.
This event is not just a swim; it’s part of a growing tradition within Tulsa Area Triathletes (TAT), fostering community and encouraging newcomers to feel at ease. The support from local sponsors like RunnersWorld Tulsa, offering discounts on essential gear such as swim buoys, underscores the inclusive nature of this initiative. Each lap around Keystone Lake is more than just exercise—it’s a step towards building confidence in open water swimming.
The course for each Tuesday night event begins and ends at Keystone Lake Shelter 2, which offers participants easy access to parking and changing facilities right by the shore. Swimmers are encouraged to use swim buoys provided they comply with safety guidelines set forth by TAT. The route is a circular path that loops around the shoreline, allowing swimmers who feel less comfortable in deeper waters to stay closer to land while still enjoying the experience of open water swimming.
Weather conditions on May 26th typically feature an average temperature hovering at about 70 degrees Fahrenheit (21°C), with wind speeds averaging slightly over ten miles per hour. The humidity remains moderate, around 73%, which can make for a pleasantly refreshing dip in the lake as evening sets in. Although there's potential for light rainfall and clouds reducing visibility somewhat, swimmers will mostly enjoy clear skies during their session.
