British star Jonathan Brownlee says winning Super League Jersey will be as hard as an Olympic medal.
Among the world class field assembling in the island alongside the Rio 2016 silver medalist are four of the other top six men from the 2017 World Triathlon Series.
Super League Triathlon is a new concept for the sport which features shorter, more spectator-friendly formats.
Jersey is hosting only the second event in the series, which debuted in Hamilton Island, Australia in March.
Women will compete for the first time this weekend with three of the top five finishers from Rio set to star.
Jonathan Brownlee, who headlines the British contingent in Jersey, finished sixth in the World Series after an eventful season, but says the new format of Super League should suit him.
