Event overview

Thousands of adventurers have taken on the London Summer Walk or an Ultra Challenge® - the UK’s biggest and best series of treks and trail runs for a wide range of ages, fitness and experience levels which raises £10+ million a year for charities!

You’ll get full support all the way so you can set a new goal, conquer the capital and push yourself over 25km for an important cause. If you’re up for a charity challenge event this year, make it the London Summer Walk!

The Ultra Challenge Experience

Walk at your own pace. The level of support enables you to go further. There are rest stops with food and drink, medical and massage teams, and a fully signed route to guide you.

A finish-line celebration with BBQ meal, bar and music awaits with an amazing sense of achievement for you personally and also for your fundraising efforts.

Get Sponsored for Charity

You’ll be amazed how much you can raise on these challenges as friends and family will recognise and support your courageous endeavours and significant mileage over half marathon distance! All fundraising goes directly to your charity via an online JustGiving page.

How to start fundraising

You need to create your fundraising page on JustGiving within 48 hours of registering for your challenge. Then you can start your fundraising by sharing your page online with your friends and family.

Fundraise as a team

As long as you’re all fundraising for the same charity, you can create a team fundraising page on JustGiving. You will still have to reach the combined total fundraising amount as the target is per person, not per team.

Fundraising concerns

Speak to your charity about any worries. They are the experts and will offer you support, materials and inspiration throughout.

Remember only 50% of the target has to be reached 3 weeks before the challenge meaning you’ve got time after the challenge to impress everyone with your achievement and keep on fundraising.

Help for you

If you don’t reach the fundraising target, there are alternative options. You can always change to a self-funded place and still take part in the challenge.

Next steps

Once you've got your charity place, your details will be passed to the charity and you will hear from them within 14 days.

A great experience, which I thoroughly enjoyed, already looking to book again!

The whole experience of walking round London but with the sunrise over Tower Bridge was brilliant.
