Floors Castle Duathlon

Join us for the inaugural Floors Castle Duathlon on September 29th 2024. 

An exciting blend of running and cycling set against the stunning backdrop of Floors Castle, near Kelso, in the Scottish Borders.

Prepare to push your limits as you navigate the picturesque grounds of Floors Castle before setting out to explore the quiet rolling roads of the beautiful Borders countryside. Choose between our Standard Distance Duathlon for a test of endurance, or opt for the Sprint Distance for a quicker, adrenaline-fuelled race. Take on the challenge solo or team up with friends for an unforgettable relay experience.

Whether you're a seasoned athlete seeking a new challenge or a beginner looking to embrace the thrill of duathlon racing, our event caters to all levels of fitness and experience. The Floors Castle Duathlon is brought to you by the same team that delivers the hugely successful East Fortune Duathlon (Triathlon Scotland's Event of the Year 2023). Expect the same TriWorks attention to detail, friendly welcome and lively finish line atmosphere.

Please note, for the safety of our athletes and volunteers there will be a time cut-off of 1hr20m for the first 10km run. If you think you are unlikely to make this time cut-off we would suggest entering the Sprint Distance Duathlon instead.
