FLAT. The course is four laps around the man-made Olympic rowing lake so it is flat. Inside and outside toilets. Plenty of free parking. Concrete/ pathway course. Little man under a canopy playing his music half way around.

Brilliant first 5k. I have never been a runner but my friend and I decided to do a run to keep fit and I wanted to raise money for my partners mum who has breast cancer. I managed to raise £215! I was very nervous to do the run but after some training and support from family I made it to Dorney Lake. The organisers were very friendly and helpful and I couldnt have asked for more. The overall experience was amazing and would definitely recommend doing this run! There were water and snacks afterwards which helped bring my energy back after my first 5k. I thoroughly enjoyed the day and would do it again!

A GOOD PB COURSE. This was the first time i jad taken part in a run through event. I was a beautiful setting and was very well organised. The only thing is that you need a lot of mental strength for this one as 4 laps really test you, especially the beginning of lap 4 when you look up and all you can see is 2km of lake in front of you. The finish line becomes a thing of imagination. I did find completing it very rewarding and got a new PB of 1:53:33 All in all i would do it again!

Brilliant for a first half-marathon. This was my first ever half-marathon and I don't think I could have chosen a better run! The route itself was amazing, nice and flat and with great scenery. The staff were super friendly and helpful, and they were a massive part of the overall atmosphere. Great value for money and I would highly recommend!

Great Event All Round. I ran the Half Marathon and I thought it was a well organised event with a decent pre race warm up and atmosphere all round. Finished with a nice medal and snacks. I have already booked up for the next one.

Organised event. The event was organised well however could of had another water station on the course. 1 station was not sufficient. The warm up was good and helped group people of same level together. Disappointed the medals were all the same for 5k, 10k and half marathon.
