Triathlon Clubs

Big group discounts, waves tailored for club championships and the CTS European tour… the Castle Triathlon Series provides the perfect venue for your annual tri club’s major race day meets.

Triathlon Clubs

There is no better feeling, taking part in a race surrounded by your fellow club mates, racing against each other yet supporting each other from the start to the finish of your chosen distance. Seeing each other, high fiving as you go past on the course, hearing the whoops and yelps as you cross the finish line with your club mates cheering you on right to the end.

We want you to embrace that feeling and help you to encourage your club members, young and old, to join us at one of our six super triathlon festivals throughout the season.  Either stay on home soil and travel to one of the the four UK based events or really go for it and travel en masse to either the splendour of the Chateau de Chantilly in France or the stunning privately owned castle in Galway, western Ireland.

With distances to suit everyone from beginners to those chasing podium positions, there are options to go short or long in triathlon, to test yourself against the rest before the season really kicks off. We have added Swim only race distances of 1 mile, 2.5k & 5k as well as an off road half marathon to our line up of events for 2018.

Bring your Club to Castle Triathlon Series in 2018 and receive the following rewards:


• 25% Discount on ALL Triathlon races until April 30th – keeping early-bird prices exclusively for tri-club members.
• 25% off entry to our new Half Marathon & Swim events until April 30th
