Royal Windsor Half Marathon & 10k River Trail Run routes

Icon

Both 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 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 event 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 event 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 event 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 event 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.
  • Did the event in 2018

    the course is perfectly fine and well organised but its really expensive for what you get. 35 quid with no included parking is a little bit questionable.
  • Did the event in 2019

    the course was much longer than expected. Since I'm used to longer distances, it wasn't too difficult but this could be a real problem for some people. Fix it for next year!! Other than that the race was good & well marshaled
  • Did the Half Marathon in 2019

    Brilliant event, I will be back next year. The event was well organised, the nice weather always helps and I thoroughly enjoyed the whole experience!
  • Did the Half Marathon in 2019

    A really lovely course along the river Thames. Slightly chaotic start in ‘waves’ which didn’t mean very much as couldn’t quite hear. Some places in the first fee km the path is very narrow and you couldn’t go at your desired pace. The km markers were a bit random - not just based on my gps but several others running around me also commented they were out. So don’t trust them to keep your pace!
    That said the course was well sign posted and well marshalled with good number of drink and gel stops along the route. The atmosphere was good for a trail run but don’t expect crowds lining the route - it’s not that kind of run!

    My only very minor criticism was the last 500m after the up and over road bridge (which was a bit of a killer at the final km!) was the signposting/marshalling ran out and it was a bit tricky to know what the precise final route was as by that point you were back in the main part of Windsor with tourists milling about and children playing on the grass. So a bit more delineation in the final point would have topped it.

    All in all a really enjoyable run and I will definitely consider doing it again.
