About Longest Day
What is the Longest Day?
In 2026, the summer solstice and Armed Forces Day come together for the return of our Longest Day Challenge.
This is your moment to push past limits. Every challenge feels impossible until you break through it, and you can break through it.
This June, set a personal best. Run, walk, ride, row, swim, climb, or dive - or support someone chasing their own goal.
Every effort helps raise vital funds for those who faced their own longest day.
Make this summer count. Make it your Longest Day.
Set a goal YOUR way
Set your goal or support someone else to show up as the best version of themselves.
Add miles to your activity tracker however you want.
Making your fundraising fun
Sign-up and receive a branded wristband to get you started on your Longest Day journey.
Raise £100 or more and we'll send you a t-shirt and water bottle to help keep you hydrated.
Upon campaign completion you'll receive a unique finisher medal in the post.

You can go further than you’ve gone before this June to raise funds for those who served.
