Battersea Park Marathon, Half Marathon, 5k and 1k Junior Race

on Sunday 12th October 2025

Officially the world’s Flattest Marathon & Half Marathon

Battersea Park is one of London’s most picturesque parks and has been a favourite course for those wanting to run a PB! The course is totally flat, offering the perfect opportunity to push yourself to a personal best. Starting at the Millennium Arena, the marathon course follows 10 laps of the park before finishing back on the Athletics Track, under the Iconic RunThrough  Gantry! The Lapped course makes it easy to follow and great for any spectators to catch you flying around the course.

As always with RunThrough, you will each get a themed medal, water and post race snacks on the day. Each mile is accurately marked out with signposts and we have plenty of helpers to keep you on track and to encourage you on your way to the finish. Come and enjoy the day with us; we hope to see you there!

Make this a fun day out for the family, with our 1km Junior Race around the athletics track! All kids will also receive our sponsored goodies and shiny new medal!
