In support of Macmillan Cancer Support

We’re delighted to have Macmillan as our RunThrough Triathlon Partner in 2026. Macmillan has spent more than 100 years helping people living with cancer. From the moment someone is diagnosed, we're there with all the information, support and guidance they need, to help everyone with cancer live life as fully as they can.

We’re returning to Higginson Park for the Marlow Triathlon on Sunday 19th July 2026, following the success of our inaugural event earlier this summer.

Choose from Half Iron, Olympic or Sprint distances as you swim in the River Thames, ride through rolling hills, and run past beautiful riverside views. This summer edition promises the same electric atmosphere and top-tier racing experience.

With RunThrough, you can expect a lively event village and clear guidance from our on-course team. After your run, enjoy food, drink and free finish-line goodies from our partners.

You can add an official event t-shirt to your entry at checkout for more than 30% off. Produced in partnership with RT Kit, it features the event logo on the chest and is the perfect keepsake to celebrate your race. Offering the t-shirt as an optional extra helps us keep entry costs lower for runners who prefer not to include merchandise.

Once you enter, you’ll receive a confirmation email straight away, and full event information will be sent to you closer to race day.

We look forward to seeing you on the start line.
