Stefannie Gillespie is set to defend her Legend of the Lake title as the open water Ocean Swim series hits Rotorua.
The only fresh water swim of the series, Gillespie (Matamata) won the event a year ago and is likely to repeat the win at 3.5km swim at Tikitapu (Blue Lake) tomorrow.
The Legend of the Lake is the third swim in the series, with Gillespie finishing second to Charlotte Webby in the Sand to Surf at Mount Maunganui then missing the second event, Auckland's Harbour Crossing.
Webby won't be in Rotorua, but Gillespie's challenges are like to come from Claudia Ashby (Hamilton), Sammy Winward (Auckland) and Bridget Maher (Auckland).
The men's race last year was won by local favourite Kane Radford who won't be defending his title.
