The Thames Meander - Autumn is a flat riverside race series in Richmond, commencing and concluding at the Petersham & Ham Sea Scouts HQ on Petersham Road. Participants can select from 10km, half marathon, or marathon distances, with all three utilizing the Thames Path towpath for out-and-back courses.

The 10km turnaround point is at Kew Gardens Car Park on Ferry Lane. The half marathon extends to the Thames Path opposite Barnes Sports Club. The marathon follows the same 13.1-mile out-and-back course as the half marathon, run twice.
