246 reviewsAn excellent event low key event which delivers as well as larger events.
Please pass on my thanks to all the marshals, helpers & pacers which made the event possible.
Really nice event
The volunteers were amazing; friendly, helpful and enthusiastic! The halfway support and marshals along the way helped to keep you going and I got my bag almost as soon as I crossed the line.
Not enough toilets
Well organised club race, great pacing
Good event. Would have liked a medal to add to collection rather than a hat.
I understand as the riverside path narrow runners headed off in batches. Very different to other events but a good one
Really well put together, pacers very friendly, great warm up for marathons
Very friendly,happy,helpful Marshall's
Very enjoyable .2nd time I've taken part,just a shame about the weather at the start.
Thanks
well organised event
Really good event.
Brilliant event and very well run. All of the marshals gave a huge amount of support and it is definitely open to beginners. The event HQ is very well set up and the free cakes at the end make the run well worth it.
very well organised event
pacers were fantastic. very friendly and really helped me to get a great time.
WOnderful, simple, but well organised event.
The 8.5min second group of pacers were superb. They held us together right to the end. Much appreciated.
A lovely event organised and delivered by a great bunch of people at the Clapham Chasers.
The only feedback I would give is that the very limited number of male toilets caused delays. Next year would be good to have a few more available either through portaloos or try and get the park to open another building with loos. Otherwise an excellent event with very good and friendly pacers and excellent marshals.
Superb!
A very well organised event, friendly pacers and marshals.
Due to weather conditions there was a delay at the start which wasn't very good
Really enjoyed the run and marshal were very supportive.
The only thing I would crises was the start. Having to wait in the cold and rain while having our numbers put down as needing to split up the groups was not the best start to a race,
Scenic and Atmospheric
Flat 20milers with friendly marshalls and beautiful views (with lots of mud!)
It was my first 20mile run and I really enjoyed it. Marshalls were very friendly and water stations were very frequent.
Due to the wet weather leading up to the event and also the rain on the day, the surface was sometimes muddy, but it was flat and the view was beautiful, so it didn't bother me too much.
The goody bag and cake at the end of the race was good as well.
Oh, and I received my bag as soon as I finished, I was impressed!
Thank you for all the marshalls standing in the cold, pace makers for keeping the event cheerful and organisers for running the event.
I would come back for future marathon training.
