Taking place in and around Higginson Park, this much‑anticipated event welcomes everyone from first‑time triathletes to seasoned endurance pros. With an open‑water swim in the River Thames, scenic cycling routes through the Chiltern countryside and a riverside run to the finish, it’s a challenge that’s as beautiful as it is rewarding.

With Sprint, Olympic and Half Iron distances on offer, plus relay options, there’s something for a wide range of abilities. Even if you’re not racing, it’s a brilliant day out for spectators, with a lively event village and fantastic spots around Marlow to cheer on friends and family.

And once you’ve crossed the finish line, you’ve absolutely earned a treat. Whether it’s a well‑deserved cold beer, a leisurely lunch or a celebratory bite with friends and family, Marlow is perfectly placed for post‑race rewards. Think riverside pints at The Two Brewers or refuelling with great coffee and brunch at one of the town’s much‑loved spots, The Ivy Marlow Garden.

From medal to menu, there’s no better place to toast your achievement!
