Arrival, Car Park, Registration & Waiver
All competitors are asked to park in the main car park directly behind the building. All participants must report to and register with reception. Please have a waiver signed before you arrive, you will not be able to compete without a valid signed waiver. Link to waiver below. https://waiver2.roller.app/WestCountryWaterPark/home
You will be given a race pack upon registration which will contain your race number, timing chip and an orange ankle strap. Please put the chip onto the strap and place it on whichever ankle you feel more comfortable, please put your timing chip above any wetsuit or tri suit.
Transition Zone
The transition zone will be set up on the South East corner of the lake near to the road entrance. This is a short walk on concrete and grass so you may want to wear flip-flops or trainers that you leave at the entrance to the lake to collect at the end of the race. Please be at this point at least 20 minutes before your estimated start time.
Swim
The swim will take part in our lake. There will be two separate buoy circles for the different disciplines, this will be explained in the pre-event briefing. Wait to be invited into the water by the start marshal and keep clear from any swimmers already in the water. Please swim clockwise in the lake.
Bike
You must put on and secure your helmet before taking your bike from the rack. Only remove your helmet after you have docked your bike at the transition zone. Once ready, make your way with your bike out of transition, mounting and dismounting your bike at the end of the green mat.
The bike routes are below with Super Sprint (Left) and Sprint (Right).
Marshalls will be positioned on every turning point along the route and will be wearing high-vis.
The ride uses public roads, and you must follow the rules of the road, riding respectfully and safely in relation to other road users. The road surface is generally good but watch out for holes and uneven surfaces. As a rural area, key hazards are horses and farm vehicles. Competitors must follow the rules of the road at all times. Any cyclist who rides in an unsafe manner will be disqualified.
No litter must be left at any point of the course. Any competitor seen to be littering will be disqualified and the environment agency may be notified.
Run
Leaving transition you will be directed to the start of the running track by a marshall. The run is along a pathed running track. If you are participating in the sprint triathlon it is imperative that you count your laps, there will be a wristband station at the beginning of the track, every time you complete a lap you may grab a wristband. To finish the race sprint triathletes need to collect three wristbands
Equipment Hire
We do have wetsuits, swimcaps and towfloats for hire if you need.

The lake itself is wonderful for swimming and the Aqua park looks a lot of fun. There’s plenty for everyone to do including paddle boarding and of course the go-carts !
The staff are very attentive and will happily help with any of your needs.
I was happy to find a vegan sandwich in the restaurant which many places don’t have.
Will definitely be back for more.
All the children had an amazing time from start to finish. They went on the aqua park first which they all throughly enjoyed ,one child needed help but with a quick shout to the life guard they had help immediately. They were all given very clear instructions by the staff before going on, there is a lot of mixed ages together which I was a little worried about but once on they are all spread out and it was fine. They all then went on the go karts! Most of the children were a little worried to try but the staff were brilliant helped with anything they needed and answered any questions they had and put them at ease.
It was an absolutely brilliant day had by all. One thing I will say is maybe there needs better signage everywhere as if it is your first time coming you might get a little confused on where to go for things.
I will definitely be back again real soon
The staff have a great deal of patience and contribute to the fun; it’s a great team.
We loved our recent SI event and will be back for sure🙂
