Organiser's Description

A stunningly scenic riverside race series starting from the Petersham & Ham Sea Scouts HQ, Douglas House Meadow, Richmond, TW10 7AH and heading out to Barnes on the Thames Path towpath (opposite Barnes Sports Club) then returning on this out / back route to finish back at the Petersham & Ham Sea Scouts. All three race distances are very fast, flat on a runnable route proceeding all along the Thames Path, and the course is very well marked and marshalled all the way along. The Check Points are well stocked and there is excellent medical support throughout from our KLP Medics that are stationed at the Start / Finish (Check Point 1) and at Kew Gardens Car Park (Ferry Lane) Check Point 2.

I think this is a great event and have run it a few times. The riverside route is very scenic and extremely flat. Nicely stocked drinks stations. It's not hugely oversubscribed either, so the start and registration aren't a bun fight. The only things to note are that the tow path isn't completely paved, so there are a few spots where it's more trail-like. And there are no distance markers, but that's not an issue as I track distance on my watch.

As my first marathon, I obviously cannot compare this to any others. That said, the event had a very nice feel to it, with no criticism to the organisers, it felt amateur. By this, it felt very much a run for standard runners and supported by a group of volunteer marshals. I would imagine this is what the original marathons of the 70s were like, with less than 80 participants. Re the run itself, easy to follow, picturesque and fuel stations in perfect locations. The only negatives I had was the path in places was very narrow - can't be changed - and lots of Joe public in the way. My final gripe was the race according to my Strava measured 26.7 miles and not 26.2. That said, I would definitely do it again!
