Course Description
5 Mile Swim: Around Hobbs Island
- requires the participant to provide kayak and kayaker-
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.
2 Mile Swim Event
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 just after the 5 mile swim start. 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.
1 Mile Swim Event
This is a one mile out and back that will start at the same public boat ramp as the 5 and 2 mile swim start. Start will be just after the 2 mile swim start. Swimmers will enter the water via ramps on the shoreline. Swimmers will proceed upstream 0.5 mile and then turn around at the turnaround buoy. 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 and Time Cutoffs
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 12 noon and finish by 5 hours or 1:30 pm. No time cutoffs for 1 or 2 milers.
Temperature
Water temperatures are typically between 75 to 83 degrees. We encourage you to stay well hydrated before and after, select an appropriate pace for your temperature and comfort. If water temperature exceeds 87 degrees (extremely unlikely given historical conditions), we will cancel the swim due to safety.
Spectators
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.
RULES
-
Swimmers must be at least 13 years of age.
-
Swimmers may wear wetsuits if the water temperature is 78 degrees or lower.
-
If the water temperature is between 78.1 – 83.9 degrees, competitors may wear wetsuits but will not be eligible for awards.
-
If the water temperature is 84 degrees or above, participants may NOT wear wetsuits.
-
Swimmers must wear issued swim cap.
-
The following items are NOT allowed: fins, paddles, gloves, floatation devices, or audio devices.
-
Participants may use any stroke to propel themselves thru the water and may tread water or float, if needed.
-
You may touch or hang onto a kayak for safety with no penalty against awards, but making forward progress with a kayak will be grounds for disqualification from awards. No touching other people other than incidental contact unless for safety reasons. Have your kayaker carry hydration and nutrition, and also carry extra nutrition with your kayaker in case this swim takes longer than you planned.
KAYAKERS
-
ALL FIVE MILE SWIMMERS ARE REQUIRED TO PROVIDE THEIR OWN KAYAKER TO ACCOMPANY THEM. If you do not have a kayaker, you will not be allowed to swim. This rule is for your safety as the river will be open to boat traffic. Boats will be unable to see you if you are swimming alone.
-
YOUR KAYAKER WILL NEED TO REGISTER ON THE SAME REGISTRATION SITE WHICH IS THE SAME ONE THE SWIMMERS REGISTER ON (It will show a $0 balance at the end of registration). and specify who they are kayaking for (it will show a $0 balance at the end of registration). Your kayaker will receive a race t-shirt as they are a vital part of this race. All of this is included in the race fee that the swimmer pays. We have a very limited number of kayaks donated by various members of the local endurance community that can be allotted on a first-come first-serve basis, so, swimmer or kayaker, indicate in your registration if you need one.
-
KAYAKERS MUST HAVE AND WEAR LIFEJACKETS AT ALL TIMES.
