This October, London welcomes a brand-new running experience designed to blend community, competition and high-energy thrills. On Saturday 18th October 2025, Finsbury Park will host the debut of the Endure Relays Event Series – a dynamic new concept in urban racing that puts teamwork at the heart of the sport.

The Lowdown

Brought to you by the team behind Endure24 – the UK’s iconic 24-hour trail running festival – Endure Relays London is the first in a new trio of city-based events, with Birmingham and Manchester to follow. While Endure24 is famed for its festival spirit and ultra-distance challenges, the Endure Relays are designed to deliver that same buzz in a fresh, fast-paced format.

The set-up is simple: four hours on the clock, a rapid 2.5km loop, and your crew at your side. How far you go is up to you.

Endure Relays are built for speed, tactics and camaraderie. Each course is carefully mapped to showcase the natural beauty of its host park, blending runnable trails and smooth pathways for an energising, scenic challenge.

This is racing with a twist – strategy is everything. Will you blast out early laps with minimal rest? Or pace it steady, saving energy for a strong finish? Whether you’re running with friends, colleagues, or your local run club, it’s not just a test of endurance, but of teamwork and smart decision-making.

Why Get Involved?

What makes Endure Relays unique is its accessibility. Whether you’re a casual runner or an ultramarathon devotee, there’s a challenge waiting:
• 13 laps as a team = 20 miles
• 17 laps = a full marathon
• 20 laps = the ultimate 50k Ultra

It’s about community as much as competition. As Nick Tuppen, CEO of Threshold Sports, explains:

“Running communities have boomed in the last five years. They’re built on support, sociability and the group experience – yet most races remain solo pursuits. Endure Relays flips the format, designed for the full spectrum of running clubs and crews across the UK. We had over 900 teams join Endure24 this summer, and we can’t wait to bring the relay spirit to cities for the very first time.”

For Londoners who thrive on fitness, lifestyle and shared experience, Endure Relays is more than a race – it’s a social sporting event. Think finish-line celebrations, buzzing team spirit, and the thrill of chasing distance against the clock.

And for the capital’s luxury lifestyle crowd? It’s the perfect way to combine fitness with friendship, while being part of one of 2025’s most exciting new running events.

The Endure Relays London launch takes place at Finsbury Park, Saturday 18th October 2025, with entries open now.
