Event Overview
Scheduled for mid-September 2026, the Richmond Marathon has established itself as one of the most beautiful and fastest road races in the UK. Often dubbed 'London's Prettiest Marathon,' the event starts within the world-renowned Royal Botanic Gardens, Kew, and finishes at the Old Deer Park in Richmond. The vibe is a perfect blend of high-performance racing and a festival-like atmosphere, as it forms the centerpiece of the Richmond Runfest weekend.
History buffs will appreciate that the course runs through land once owned by Henry VIII, while competitive runners value it for its flat profile. Unlike the crowded streets of central London's major marathon, Richmond offers a more intimate but equally professional experience, making it a favorite for those looking to secure a Boston or Chicago Marathon qualifying time without the logistical headaches of larger majors.
Course Details & Terrain
The Richmond Marathon is celebrated for being significantly flatter than most city marathons. The race begins with a stunning 3-mile loop inside Kew Gardens, where the terrain is impeccably maintained tarmac and hard-packed gravel paths. This section is shaded and tranquil, providing an ideal start to settle into your goal pace.
After exiting Kew Gardens, the route takes you along the historic Thames Path. This is the most technical part of the course. While largely flat, the surface transitions between paved sections and riverside dirt trails. If there has been rain in the days leading up to the 2026 event, some sections near Ham House can become slightly soft, though they remain very runnable. The middle miles feature iconic sights including Richmond Bridge and the scenic banks of the river toward Kingston.
The final 10km is where the mental battle begins. You’ll loop back toward Richmond, finishing on the grass at Old Deer Park. The elevation gain is negligible (less than 150m total), but the multi-surface nature of the course—switching from road to trail—requires strong ankles and varied training runs.
Who Should Enter? (Beginners vs. Experienced)
For Beginners: The Richmond Marathon is one of the most accessible 26.2-mile events in the country. The 6.5-hour cut-off time is generous, and the sheer beauty of the surroundings provides a massive psychological boost when the 'wall' hits at mile 20. The lack of major hills means you won't be punished by steep gradients.
For Experienced Athletes: This is a PB (Personal Best) course through and through. Elite athletes and club runners flock here for the cool September morning temperatures and the flat profile. If you are chasing a sub-3 or sub-4 hour goal, the flat riverside sections allow for incredibly consistent mile splits. The only challenge for veterans is managing the slight narrowness of some Thames Path sections, requiring tactical positioning in the first half of the race.
Coach Raye's Race-Day Pro Tips
- Pacing Strategy: The 'Kew' Conservation. Do not get carried away by the beauty of Kew Gardens in the first 5km. It is easy to run too fast on the perfect tarmac while the crowd is cheering. Bank your energy for the Thames Path, where the terrain becomes slightly more energy-sapping.
- Shoe Selection: The Hybrid Choice. Since 70% of the course is on hard surfaces but 30% is on riverside trails/grass, choose a road shoe with decent grip or a 'road-to-trail' hybrid. Avoid super-smooth racing flats if the forecast calls for rain, as the river paths can get slippery.
- Nutrition: The Salt Factor. September in London can occasionally produce 'Indian Summer' heat. Ensure your nutrition plan includes electrolytes to manage the humidity often found near the river. Start your salt loading 24 hours before the starting gun.
