Did the race in 2021
First time doing an event. All very well communicated before hand and knew exactly where to go and what to do. Lots of parking. Good transport to the start. All the volunteers were very friendly and helpful. Good course, mainly trail paths and a few field cuttings. Only thing I'd say needs improving was the amount of bins on the course, there weren't many at all so had to carry bottles from the water stations quite a way before being able to dispose of.

Down Tow Up Flow is a great HM - the route along the Thames from Windsor to Marlow is stunning and the organisation is always excellent.

After much faffing about logistics we booked the coach transfer to the start. This was so easy that I couldn't believe how complicated we had tried to make it!Quick and easy registration and this was all in the same area as the baggage drop, the coffee van, the loo's & the start. Fantastic!The route was fab and the marshalls were all friendly and encouraging.Lovely medal at the end, with a banana, a bottle of water, haribo and even a sack of Epsom Salts! Windsor was fab place to wander around afterwards. We had a hot drink, lunch & an icecream in the park and by the river.A wonderful day was had by all - thank you!

Did the race in 2018
It's a beautiful course along the river. Would definitely do it again. Despite the fact it was hot and I hadn't really trained, I managed a good time. Would highly recommend.
Did the race in 2018
Very well organised, beautiful course but not one for the hard-core runner wanting that PB - course very varied,some steps,bridges etc. Would definitely recommend.
Did the race in 2018
I do think adding fresh fruit ( orange slices ) could be very helpful to the participants instead of Haribos... I also was hoping the timing would've been tracked so that I could know how I did through the race.. and not just my finishing time.. if I had known in advance I would've tracked it myself...
Did the race in 2018
The course was epic. Marshalls were helpful and very encouraging. However, I was a little disappointed by the lack of a banana at the end. Sweets just aren't as good!
Did the race in 2018
lovely route just take in to consideration that there is a bit of stopping and starting along the route as its very busy with walkers walkers..gates and few roads to cross
