I have a disability can I still participate?

We are an all-inclusive event and do our utmost to accommodate participants with disabilities.  Please contact our Customer Service Team, with a description of your disability. We will assess this and establish if it is possible to compete and what we require to make this feasible.

Does any part of the entry fee go to charity?

Your entry fee covers the staging of the event and third party insurance.

When should I receive my race pack?

Your race pack will be delivered to you in plenty of time before event weekend. Team relay captains will receive the race pack for their whole team.

If you have not received your race pack before Friday 17th May, please email our customer service team on [email protected]

When will my merchandise arrive?

All clothing merchandise will arrive around mid-May. We are unable to accept any merchandise refund requests placed after March as the orders would have already been sent to our merchandise supplier.

You can perchase any merchandise in the lead up to the event even if you have already registered for the event. In order to do so please go to your profile page at

ITab medal inserts ordered at point of entry will be dispatched after the event.

Do I need a wetsuit?

Wetsuits are compulsory for this triathlon for the safety of our participants. Your wetsuit will keep you warm and improve your swimming speed; a wetsuit provides you with extra buoyancy and the higher you are the faster you swim. Your wetsuit must be a neoprene and we recommend a full body wetsuit, it can be a ‘shorty’

Can I listen to a personal music player whilst racing?

No. You will be unable to hear other competitors or the marshals when you are wearing one and consequently pose a threat to others.

Is water available during the races?

Water will be handed out on the run course and at the finish line.

There will be no water stations on the bike course – it is your responsibility to ensure that you have enough fluid to keep yourself hydrated on the bike leg.

Who do I contact for lost property?

Please contact the event organisers via email: [email protected], with a full description of the missing item and we will do our best to reunite you with the item.

    Fantastic event all round. Great for a first tri. Lovely swim, then nice to cycle on closed roads. Transitions can feel long but apart from that excellent course.

    What can I say? Ideal setting, great organisation well thought out course and closed roads! And not to mention the most regal of transition areas. The only negative is the cost for spectators (£40 or thereabouts for two)
  • Did the Sprint - Saturday in 2019

    Fantastic event, it gave a real sense of being part of something epic and special. Organisation, marshalling etc was fantastic and flawless for such big event !! Cant wait to do it again next year !!

    Please put some padding down over the red matting where you rack your bikes! I really hurt my foot when I trod on a stone!

    Did the Sprint - Saturday in 2019

    First time doing this event and from
    the start it was a great day. The event as a whole was very well organised and coordinated. Event area loaded with stands an stalls and plenty to do for the kids. The event itself was layed out well, really enjoyed the cheeky uphill run after the swim to transition. Transition was well organised with no areas were a #hangingout triathlete could go wrong and both the bike and running routes being enclosed challenging but fun. Further loads of first time and experienced triathlete took part which made for a great atmosphere. One piece of advice is to arrive as early as possible, I had 2 hours which ment for a non rushed look round, checking swim start, finish, transition entry exits and as it's a lap course noting where I had to cut of or merge on both the bike /run routes.
    Recomend this event to anyone.
    Challenge yourself or stay the same !
