Tri’ your best in 2018: Time to give triathlon a go

Win a free triathlon

December 18, 2017

Every year we welcome thousands of first time triathletes, just under a third of the entire field.

We pride ourselves on offering both a perfect distance, that allows competitors to literally dip their toe’s in the water of triathlon, and a nurturing team who provide support from the moment you sign up.

The New Year is a great time to take on a new challenge, seasoned triathletes now take part on the Castle Triathlon Series, after taking up the sport for the first time for a special reason. These reasons include everything from raising money to a meaningful charity, getting fitter or losing weight, or taking on a personal challenge to prove your own mental and physical strength.

To make sure you can take the challenge, we do our bit to make it easier for you, for instance:

  • You can hire all the gear from wetsuit to bike
  • There is a distance for all levels of fitness including a Starter Triathlon
  • You can do by yourself or in a relay team with mates
  • You could set the target of five in one year – one a month from May!
  • We can offer you personalised training support
  • You could raise money for charity too, our charity partner Macmillan Cancer Care will give you a FREE place/s in return for fundraising; then you will get serious bragging rights!
