There will be multiple safety kayaks placed along the course. It’s a great time to come out and race!

Race Timeline - TBD

Race Type:
 
This is an Open Water lake race. Each event will start in the water from a dock entry/timed start. It will be swum in a counterclockwise direction with buoys staying on your left shoulder.  The finish will be a dock exit.

Athletes should wear brightly colored caps for this event - all participants must wear a cap.

Each participant will be given a race number at the check-in phase of race. That number should be written on their upper arms and on the back left of the shoulder in Sharpie or waterproof marker in 3–4-inch height. Participants will check-in and race numbers verified prior to entry.  

If you are planning on swimming more than one event, you need to be able to swim an 800 in less than 30 minutes.
 
Warm-up:
 
There will be an open warm-up and warm-down in a restricted area. The separate warm-up area will be open for the duration of the event – NOT RESTRICTED TO A CERTAIN TIME. All participants will enter the starting dock at the designated warm up area and be directed by a lifeguard into the water off the starting dock, swim the course, and exit the water one at a time onto the finish dock. Any participant who would like to warm up more can line back up at the starting dock for another loop. Participants will be asked to walk from the warmup area to the competition area and are expected to arrive at the competition entrance at least 10 minutes prior to their assigned race start time.

Safety:
 
Rescue personnel will be in kayaks positioned at each turn buoy and at the start and finish of the race. There will be one motorized water-craft monitoring the course throughout the race.  All rescue personnel will have lifesaving buoys throughout the race. There will be lifeguards positioned at the warmup area and at the actual race start/finish site.  Water will also be available for emergency situations on the platforms.
 
Medical Evacuation Plan:
 
If a participant is struggling or needs assistance, they should swim to the nearest shoreline and wait for the safety staff to arrive.  If unable to make it to the shore, the participant should wave their hand and stay in the same location.  Rescue personnel will come to their assistance.  Participants will then be transported to the nearest shoreline or finish line by kayak.  An EMT and ambulance will be on site to treat any participants if necessary.
 
Weather:
 
The race will be swum under all conditions except thunder and lightning.  If there is hazardous weather in the area, we will delay the race 30 minutes per occurrence. We will make every attempt to swim the events. There will be no entry fee refunds.
If there is hazardous weather during a race, foghorns will be used to alert participants to exit the lake at the nearest point. Participants are to meet back at the registration area and proceed to their vehicles.
