Endure Relays 2025: London

Running is a team sport at Endure Relays. With four hours on the clock and a rapid 2.5km course, the stage is set for you and your crew to go the distance. Whether you’re first-time fun runners or marathon vets, the only question that matters is: How Far Will You Go?

The 2.5km course is built with speed in mind, mixing runnable paths and trails to showcase the very best that each urban park location has to offer. This is a race against the clock, so tactics are everything! Do you go out hard, banking rapid laps with limited rest in between? Or aim for a team negative split, managing your efforts before a late kick? However you run it, the clock never stops, so it’s time to get scheming!

Everyone is welcome at Endure Relays! Whether you’re a ‘one and done’ powerhouse or a long-distance cruiser, there’s a spot for you in the ranks. Run 13 laps as a team to bank a 20-miler, 17 for the Marathon, and for the ultimate challenge, complete 20 laps to achieve the hallowed 50k Ultra!
