Formed in 2009, the Castle Race Series has swiftly established itself as one of the UK’s largest triathlon series.

Hosted at a selection of stunning and iconic castles across the UK, Ireland and France, the Castle Race Series events all promise an inspirational and memorable race experience. For the absolute beginners and children to the professional triathletes, the Series offers a wealth of race distances to suit all levels. We’re immensely proud of the iconic backdrops to each Castle Race Series race and the friendly festival atmosphere produced at every event. We pride ourselves on offering a bespoke and tailored weekend for all those wishing to take part and grateful for all those who want to be involved on the day.

The Castle Race Series is brought to you by an incredibly dedicated team who work throughout the year to make the races the best they can be.
