Fantastic venue at Box End, simple, easy registration and well organised throughout. Plenty of changing facilities and refreshments available. Instructions were given in a clear manner, preparing me for my first race. The course was clear with bright buoys and wide enough for all the different race distances.
Great event - I shall be back!

Friendly atmosphere and no pressure so I could happily achieve my personal goal.
Definitely I'll come back next year.
Also, it's an amazing place not just for swimming, the whole family could spend nice time around

This was my first event and I was quite nervous but I thought this event was really well organized. It felt very safe, with plenty of safety kayaks around. It was a great venue and there was lots of kind support. 10/10. Well done and thank you.
