Races summary
Here's what races are available for Royal Windsor River Trail Run - October
Half Marathon
Route information
All 3 courses start and finish at the foot of the beautiful and historic Windsor Castle, current home of Her Majesty Queen Elizabeth II.
The flat course is mainly run along river trail paths and will incorporate many of the key landmarks that have made this area so famous. Some of the highlights include Boveney Lock, Bray, Dorney and Eton.
The course is not designed to be the classic gruelling cross country through puddles and deep mud. Instead it is a fun, friendly and fast trail run through some of the most beautiful countryside the Thames Valley has to offer.

Did the Marathon in 2021
Poorly marked, marker arrows in puddles, arrows pointing the wrong way,blocked by groups of people and cyclists, aid stations were awful, course was unclear, absolutely no atmosphere, awful for spectators, embarrassing event
Did the Half Marathon in 2021
Lovely people on the course handing out water, sweets and directions! Thank you for your support and help!
Did the Marathon in 2021
This event would be okay for a half marathon but for a full marathon (2 laps) it was somewhat underwhelming. No atmosphere (not even music at the start line/finish), generic medal for all race distances, and a very lonely run. The first half of the loop is pretty but the second half is a bit boring (particularly on the second lap!).
Did the Half Marathon in 2021
Firstly, the positives; lovely course, great views and location. Set up was good, plenty of water stations.Now the negatives; tricky course, lots of tree roots, slippery mud (I fell over once, my fault, you couldn't afford toi take your eyes off your feet along some parts of the course), distance markers (I know there were 3 events (10k, HM & Marathon) but the marking was bizarre, unhelpful and misleading), distance (I measured 13.47 which is a long way off), signage / marshalling (often not there when needed especially at the end when there was contrary signage and no marshals, it made for a very stressful and angry finish during which time I lost out on time and placing).Overall, better signage and marshalling would have made all the difference. Great location but spoiled by these factors

Did the Half Marathon in 2019
It was a great experience for my first half! It went well and everyone was so supportive and encouraging along the track. I appreciated the beautiful views and flat terrain. I made some great friends along the way and I felt great after completing it.My only 2 suggestions would be:- More aid stations; perhaps every 5 km would've been better if it wasn't possible to have more. Ideally every 4km would've been good. It was sort of stressful coming across injured people who didn't know when or where to get assistance (for anything from needing plaster to sprained ankles).- Instead of using gels in addition to water, offering an electrolyte drink instead or offering lollies for that extra energy. As I had not trained on gels, I did not want to take one in-case my tummy didn't agree! so I was starting to feel like my sugar levels were dropping. I have definitley learnt from this race, not to rely on the event for what I need in terms of wellbeing and that I should carry with me my own water, lollies etc to get me through; which is a fantastic thing to do anyway, so it was definitely a positive.My husband and I really like the medals too, they are really neat! As we factored this run in to our holiday (as we travelled over from NZ to visit friends); I would 100% do this run again as I really enjoyed it!!
Did the 10k in 2019
I though the course was beautiful and the stewards were very friendly. Could have wished for better weather, but that's what next year is for!
Did the 10k in 2019
Fantastic stuff. I was a bit nervous about this one but I had a really good time. Felt very strongly about coming back and leaving a review for this one. Shall be doing again. Love this site for booking as well, very helpful!
Did the 10k in 2019
Course was absolutely fantastic! Stewards were great, and the other runners were all friendly people. I'd definitely recommend it to anyone!
Did the 10k in 2018
Not one of the best experiences I've had at a race. The course was nice enough even if it was bit long by my watch, but the stewards weren't very friendly and the finish wasn't very lively afterwards either
Did the Half Marathon in 2019
Great event. Really enjoyed it. Please thanks those who organised and run it. Two minor points - the amplifier speakers didn't work (they were very quiet) for the briefing and £5 just to keep you bag is a bit much when you have spent over £40 on entry fee.

Is there a map of the marathon, or is it 2 laps of half.

What's happening in October 4th is this going ahead and if so is it a staggered start? Are spectators allowed?
Manon VT
Looks like it's actually been postponed to November 29th due to council restrictions. I think all of F3s races have staggered starts now so they probably will for the postponed event, too. Not sure about spectators though...

So am I right thinking once booked online we need to come and register on the Friday or Saturday?
Steph Ede
Hello, paying for the entry confirms a place for you at the race, they ask you to come on the Friday and Saturday to register but also to pick up your race packs. This is also a good time to assess the course and any last minute preparations before the race. Best of luck!
