The start, the swim, much of the run and the finish are all conveniently located together, making excellent spectator viewing at Grafham Water Reservoir. The swim takes place in the lake consisting of a two lap course that is easy to navigate; a quick Australian style exit on each lap makes a great spectacle for your family/friends to support you from.
Once you are out of the water you are straight out on your bike. The roads around the villages offer great surfaces for fast riding and only the odd short climb to challenge you. The bike course will be fast, but don’t underestimate it – especially if it’s a windy day!
On returning to Grafham Water, you will conquer the multi-lap course around the edge of the lake comprising of both tarmac and hard compound tracks that offers a feed station every two miles or so and is lined with supporters willing you all the way to the finish line.
There will be live commentary, music and photos as you celebrate your achievements with your friends and family.

My first middle distance triathlon. Such a beautiful location. The support from marshals and event team was fantastic. Would highly recommend. Nadia
Great event! I've taken part a few times. Really friendly support all round and everything is really straightforward.
I like a "no-faff" race and this is great. Turn up, park on site, pick up pack, rack and go! Michelle
Really enjoyed the event - Marshall's and stewards very incredibly helpful and friendly. Good surroundings - leafy lanes and a pretty reservoir. Lydia
