Race Review: Lock to Lock Swimrun

The Lock to Lock Swimrun is set in the heart of Oxfordshire along the tranquil River Thames. We have given this race a 5 star review. Read on for the detailed breakdown. Our thanks to Race Director, Darrin for providing images for this article. Next race on: September 22nd 2022.


This is a very good swimrun. The half-stump is perfect for those trying the sport for the first time and the full-course offers a challenging and varied course. We really liked the friendly atmosphere which is amongst the best, if not the best of any swimrun we have attended. The race is good value for money and appeals to both new and experienced swimrunners.

Selection of glorious cakes at the end and the family friendly feel to it.


We would like to see pairs encouraged as the standard racing format.


The Lock to Lock Swimrun is certainly not the wildest out there but it’s beautiful in its own right. The course meanders along the River Thames, with quiet and peaceful river swims going along with the flow of the current. The trail running is fun and challenging (up hill down dale). This is a well run event and there are a good number of safety boats mainly kayaks keeping an eye out for you on swims. Marshall’s are supportive and helpful, the course is well marked with no ambiguity. The finish line area is unique with homemade cakes and there is an exceptional atmosphere throughout the event. The Lock to Lock Swimrun returns on: September 22nd 2022.
