Join us on 28 June 2025 and help us celebrate Armed Forces Day 2025 in true military style with our unique (and award winning!) walking event: The 13 Bridges Challenge.

Anyone who’s walked this stunning 10-mile route through London before will tell you that there’s no other challenge quite like it; it’s a truly special event, bringing together people of all ages, backgrounds, and abilities (and a few dogs) to show appreciation for our military community and all they do for us.

Start times for the event are staggered every 6 minutes between 8am and 1pm, when you register for the event you will be able to choose a start time that works for you! If you would like to walk with friends or family please ensure you all book onto the same start time.

Registration Fee: £20 adult, children go free (Under 18)

Fundraising Target: £50

(Please note: If you sign up after Sunday 8 June 2025 your welcome pack including your t-shirt, race number and brochure will not be sent out in the post to you. You will need to collect this from the registration desk on the day).

What Can I Expect on the Day?

You’ll set off from Trinity Square Gardens near Tower Hill. Upon arrival you’ll be greeted by the friendly SSAFA team to get you checked in and join your troop.

This is a very communal event; you’ll be part of a group, so even if you sign-up on your own, you’re never alone at 13 Bridges Challenge.

And that’s it, you’re on your way!

You’ll then walk with your group, following your route map along a criss-crossing route covering 13 of London’s most iconic bridges. Around the course, at each end of the bridges (and any other tricky points along the route), there will be Military Event Marshals, there to show you the way and chat to you about their roles within the military. One of the best things about taking part in London, is you never know what you’re going to see. You might get the see the incredible site of Tower Bridge rising to let ships through; one year our walkers got to see scenes being filmed for a new action film! So, keep your eyes peeled!

And when you reach the finish line you’ll be greeted with a roaring cheer-squad celebrating your incredible achievement. Now you get to enjoy some food, entertainment, and the chance to learn more about our Armed Forces while taking a well-earned rest!

You’ll be fully supported by Team SSAFA, receive your 13 Bridges Challenge t-shirt and medal to show off, and have a great time all while supporting our Armed Forces community! Sign up today and be part of this amazing experience.
