Stunningly scenic riverside races heading out to Barnes along the Thames Path towpath on an out-and-back route.

All routes are very flat, fast, invitingly 'runnable' and well-marked and marshaled all the way meaning no navigation required.

The check points are well-stocked and there is excellent medical support throughout with a great atmosphere at the finish line.

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

Beautiful views of the River Thames on an easy to navigate, 2 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 event that I will be sure to run again. Jackie S

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
