NOTE: 5 mile swimmers MUST complete the swim in under 5 hours (12:30PM) and MUST be at the tip of the island (the turnaround point) at 3.5 hours, or 11:00 AM. Race Director reserves the right to pull you after that time.
This is a five mile circumnavigation of Hobbs Island that will start at the public boat ramp, 1000 Hobbs Island Rd SE, between Forrest Paddle Boarding (swimmer/spectator parking) and Pit Stop Boat Ramp Public Parking (volunteer parking). Swimmers will enter the water via a boat ramp on the shoreline and will swim clockwise around Hobbs Island and finish at the same location as the start. Because the first few miles and the last few hundred meters are against the river current, this swim may take longer than a typical 5 mile swim in the pool.
This is a two mile out and back that will start at the same public boat ramp as the 5 mile swim start. Start will be at approximately 7:45 AM. Swimmers will enter the water via a boat ramp on the shoreline. Swimmers will swim upstream approximately 1 mile and then turn around. The finish location will be the same as the start. Because the first mile is against the river current, this swim will take longer than a typical two mile swim in the pool. Please be aware that this is NOT an event for beginner swimmers. You should be able to swim 2.5 miles continuously in a pool before tackling this 2 mile event.
This is a one mile out and back that will start at the same public boat ramp as the 2 and 5 mile swim start. Start will be at approximately 8:00 AM. Swimmers will enter the water via a boat ramp on the shoreline. Swimmers will proceed upstream .5 mile and then turn around. The finish location will be the same as the start. Because the first half mile is against the river current, this swim will take longer than a typical one mile swim in the pool.
Current in the Tennessee River normally varies greatly because this stretch of the river is controlled by Tennessee Valley Authority (TVA) via flow rates from the Guntersville Dam. However, every year we submit a flow reduction request to TVA for the race. NEVERTHELESS, they do not have to honor this, and they may not, and we have minimal input into this decision. We are grateful that they are often able to do this for our safety and comfort. For your information, typical TVA-adjusted flow rates for this race in the past have been ~19,000 cubic feet per second, which translates to a very reasonable current for most open water swimmers. That said, be prepared to swim longer than a typical 1, 2 or 5 mile swim in the pool. The 5 mile time cutoff is the tip of the island at 3.5 hrs or 11:00 AM and finish by 5 hours or 12:30 PM. No time cutoffs for 1 or 2 milers, although the Race Director may pull you at any time if they feel that your safety is in question.
Water temperatures in mid-September are typically in the mid-70’s. We encourage you to stay very well hydrated before and after, and to select an appropriate pace for your temperature and comfort.
Register by August 31 to guarantee your shirt size! We will order extra shirts, but we cannot guarantee you a shirt or the correct size unless you’re registered by August 31.
There is a small spot near the swim start/exit for spectator, however, it is very rocky and uneven terrain, so please use caution. There is also viewing at Old Madison County Marina, which is more stable, but not accessible from the swim start/exit by foot.
