Longest Day 2025 pre-registration
As the sun reaches its peak on the summer solstice and we honour our military community on Armed Forces Day, the Longest Day Challenge returns for 2025 - bigger and bolder than ever.
This June, challenge yourself to go further than ever before. Run, walk, ride, row, swim, sail, or drive - set your own goal and push past your limits in support of those who have served.
Every step, every stroke, every mile makes a difference. Are you ready to take on the challenge?
The Longest Day challenge
Get creative and challenge yourself this June whilst raising money and awareness for Walking With The Wounded.
