Parallel Windsor 2026

The UK’s most inclusive fundraising festival

If you thought fundraising events were only for solo, hardcore physical challenges, think again. For the first time, The Lily Foundation are delighted to offer guaranteed places at Parallel Windsor – an award-winning, fully accessible fundraising festival designed for all ages, health conditions and abilities.

Why Parallel Windsor is different

Set against the majestic backdrop of Windsor Great Park, this isn’t just a race; it’s a celebration of inclusion where the motto is ‘Start Together, Finish Whenever’. There are no cut-off times, only support and shared joy. And every mile you cover helps us provide vital support and hope to affected families.

  • Inclusive events for everyone: Choose your distance – 100m, 1k, 5k or 10k. Whether you prefer to run, walk, push or wheel, this course is yours to conquer.
  • The SuperSensory challenge: A unique event specifically designed for neurodiverse participants and those with multiple learning disabilities. Engage the senses through a series of interactive challenges focusing on sound, taste, touch and smell.
  • A festival atmosphere: Beyond the finish line, enjoy a full day of entertainment, food, live music, dance and a dedicated sensory zone.
  • The royal treatment: Experience the beauty of Windsor Castle as your backdrop while you tackle your personal goal individually or as a family. 

Entry includes:

  • Official Parallel Windsor t-shirt
  • Finisher’s medal
  • Goody bag
  • The incredible feeling of supporting The Lily Foundation’s mission

Anybody of any age can take part in Parallel Windsor.

For the 100m and 1km events, participants under the age of 12 need to be accompanied by a paying adult. For the 5km and 10km challenges, participants under the age of 16 need to be accompanied by a paying adult.
