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 format is straightforward: run alongside the river, turn at the designated checkpoint for your chosen distance, and return to the original finish area. 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. The path is suited for consistent running, not technical trail running, and as a public thoroughfare, runners will encounter walkers and cyclists. Marshals are stationed along the course and at turnaround points. Checkpoints provide gels, drinks, electrolyte powders, and high-energy food. KLP Medics are present at the start/finish and Kew Gardens Car Park.

The Chelmsford Marathon & Half Marathon begins at 9:00 am in Chelmsford, Essex. Both distances follow accurately measured, undulating road courses. This autumn race offers a marathon or half marathon option and attracts over 1,500 participants, establishing it as a significant event on the Essex race calendar. A six-hour cut-off defines the marathon structure, and pacers are typically available for both distances if sufficient numbers are confirmed. The route departs Central Park via tree-lined avenues, then proceeds onto rural country lanes. This provides participants with a blend of town running and Essex countryside, distinct from a city-centre circuit. The courses are frequently chosen for good-for-age qualifying attempts, though their undulations prevent them from being a flat time-trial course. A substantial aspect of the race involves fundraising for Little Havens Children's Hospice and Havens Hospices, organizations supporting individuals with complex or incurable conditions. Runner contributions generated over £53,000 in a recent running. Participants can select a HAVENS HEROES ticket, which incorporates a donation, and the race also relies on hospice supporters and marshals within the event village.

The Gatliff Marathon is an annual challenge walk, jog, or run based in Edenbridge, Kent, starting from Edenbridge Cricket Club at Blossoms Park.

The route primarily follows footpaths and tracks through the Kent, Surrey, and Sussex countryside, requiring participants to navigate using directions instead of following closed roads. Checkpoints are included, and walkers, joggers, and runners begin at staggered times throughout the morning. Having been held for over forty editions, the event has the character of a long-standing local challenge rather than a large-city race.
