We partner with event organisers to host swim, bike and run events across the UK which reward participants with climate impact.
Every run, swim or cycle event contributes to planting trees, removing plastic from the ocean, or sequestering carbon from the atmosphere.
Our in-person events are a great way to show up for the planet and yourself.



Alongside removing plastic from the ocean and planting a tree for every ticket sold, our event villages feature a selection of eco-conscious brands who want to help consumers make better choices with their sportswear and nutrition.

Take part in our events at iconic locations where legends have gone before. Dorney Lake is just outside Windsor and hosted the 2012 Olympic rowing competitions, and now you can run, ride and swim there too.

Each of our events has climate impact attached to it. At our last event we removed 250g of ocean plastic (20 plastic bottles) for everyone joining our Climategames challenge and crossing the finish line. We also plant a tree for each ticket sold.

We plant one tree for every ticket sold, and every participant helps remove plastic from the ocean.
This exciting multi-sport festival lets you choose from triathlon, aquabike, duathlon, swim, and run events across multiple distances. Set at the spectacular Dorney Lake near Windsor—flat, fast, and smooth-surfaced—this is one of the UK’s most exciting multisport events, launched in 2023.
The event also features a vibrant shopping village, food and drink stalls, and a live DJ. Spectators can enjoy fantastic views from the lakeside, boathouse, and iconic Olympic bridge.
