10K Relay: Wetsuits/tri kits/swim skins (Ironman swim regulations) are allowed for this swim. Swimmer #1 jumps from the boat and swims the first 5K to the relay exchange while swimmer #2 kayaks alongside for support. At the relay exchange, swimmers and pilots are allowed to exit to shore for wetsuit purposes and exchange gear.  There will be plenty of volunteers on hand to assist. Swimmer #2 will complete the swim, with the traditional touch/slap/kiss of the finish arch. 

10K Solo Swimmers:  This race will follow English Channel swimming rules. This means: 1) No swim suits below the knees or shoulders; 2) No wetsuits or suits that provide buoyancy; 3) No swim aids; 4) There is to be no contact between you and your pilot's boat or other swimmers.

** All swimmers (relay and solo) must provide their own kayak or SUP and nutrition.
