The vibe at London 100 earlier this year was amazing. If you don't believe us, then hear what some of our runners had to say,
“I thought the London Marathon was the peak… then I ran the London 100. Game changer.”
"A crazy running adventure in the middle of one of the greatest city in the world"
"A test of endurance supported by some of the nicest people in this fair city"
Checkout our RaceCheck Reviews. The experiences of last year's participants will hopefully give you that extra motivation to press ENTER.
Thank you once again for supporting central London's ultramarathon. We can't wait to welcome you to London 100 (2026).
