Looking for a challenge that’s as meaningful as it is memorable? Lace up your trainers and join Team Lily for the Royal Parks Half Marathon 2025!

  • Stunning scenery: the 13.1-mile route takes in many of the capital’s world-famous landmarks on closed roads, and four of London’s eight Royal Parks – Hyde Park, The Green Park, St James’s Park and Kensington Gardens.
  • Make every step count: by running for The Lily Foundation, you’re not just taking on a personal challenge – you’re helping to fight mitochondrial disease. Your support will fund life-changing research and provide vital support to families affected by this devastating condition.
  • Achieve your goals: whether it’s your first half marathon or your 50th, this is your chance to push your limits, get fit and accomplish something amazing.
  • Join our community: with fundraising tips, cheering squads to keep you going on the day and the encouragement of a community that’s passionate about making a difference to those affected by mitochondrial disease.

We have limited places available through our partner, Run for Charity. But hurry – they’re filling up fast.

Together, we can go the distance to fight mito and find hope for everyone affected.
