Road shoes

Road shoes are definitely recommended for this course as 80% of it is run along asphalt paths and the rest on very hard packed dirt trails, so you can easily run this in road shoes or hybrid trail shoes.

Overview

The Thames Meander event is a stunning riverside race series starting in the Small Profit Dock Gardens (Barnes) which is adjacent to the Barnes Sports Club Race HQ. 

The run route starts within the park area at the Small Profit Dock Gardens and heads out across Barnes Bridge towards Kew Gardens along the Thames Path trail all the way to the Petersham & Ham Sea Scouts on this very scenic out-and-back route.

All distances are very fast, flat, and runnable, along the Thames Path, and the course will be well-marked and marshalled all the way. The check points will be well-stocked, and there will be professional medical support.

An absolute stunning location with great facilities to prepare for a marathon. A very well organised event and a very friendly Race Crew. Thank you for a lovely few hours on the Thames. I shall return. Heather

Beautiful views of the River Thames on an easy to navigate, two lap out and back, flat course. Small, friendly event with plenty of encouragement from the other runners at the turn around points. Well stocked, frequent aid stations. Range of participants from first timers to 100 marathon club runners and suitable for all. Fun, well organised events that I will be sure to run again. Jackie

This is a wonderful event, small, extremely friendly and welcoming to both the experienced (me) and first timers. I thoroughly enjoyed it and recommend it highly. Thanks to the race team who did a super job. Chris T

This is my 3rd Thames Meander half marathon. I really like the river location and route - especially the new route which takes you directly back to the start/finish. Millie M

My first half marathon and it was overall a great experience. The course offers lovely views along the Thames, not crowded at all and a friendly atmosphere. Chris L

Loved the idyllic route by the river and the fact that it was not crowded at all!!! Also the path was for the most part paved, so no deep mud and puddle bits even though it had just rained quite a lot beforehand. Super happy overall! Very friendly atmosphere from participants, organisers and helpers! Nassia F

Enjoyable event with friendly staff at registration and at the feed stations. Good atmosphere amongst the runners and encouragement from small pockets of support out on the course. Gordon N

The Thames path from Ham up to Putney takes in a lovely route. Volunteers were ultra enthusiastic on this race and the aid stations were excellent. It was muddy and windy but I really enjoyed it! Harvey G

Thames Meander was my 2nd Full Marathon and I really enjoyed it, the course is generally a flat one. Christopher J
