Make this Easter one to remember – challenge yourself and raise vital funds for families living with mitochondrial disease. Choose from a 50km Ultra, a 25km trek or a 10km challenge, and enjoy the stunning sights of Windsor and beyond at your own pace.

Starting at Windsor Racecourse, you’ll journey through the Great Park, take in majestic views of Windsor Castle, follow the Thames Path and soak up the countryside – all with full support and a celebratory finish at basecamp. And just think of all the Easter eggs and hot cross buns you can indulge in afterwards!

Every step you take helps fund life-changing support and research. sign up today to support The Lily Foundation and make a difference.
