Great event and great staff, couldn’t have asked for better. Rhys F
I enjoyed the course, and the morning out. Good - lovely clear water in the swim - nice bike route, very scenic and pretty flat. Emily V
So well organised, brilliant bike route, grass run route. Super marshals, excellent free photos. Thanks Guys! Jo C
Excellent location. Great parking - hassle-free. Plenty of space in the park. Plenty of space in the transition area. Lake swim is great. It was sunny so hard to see 2nd buoy swimming into the sun. Steep exit - for me anyway. The cycle route is good. Good signposting and a marshal on most turns. Run is great through the park and trees. Very different from most others. It is a bit tough, but worth it. Nb you won’t get a pb on the run! Thoroughly recommend. John T
Now in my 25th year as a triathlete, I estimate that I have completed perhaps 100+ triathlons including 6 world qualifiers (Bermuda cancelled last year!) and this has to be one of the most enjoyable races on the circuit. Graham P
