London Marathon 2027

Be part of one of the world’s most incredible running events. The TCS London Marathon 2027

Take on the iconic streets of London, soak up the unbelievable atmosphere, and experience the roar of the crowds as you make your way past some of the capital’s most famous landmarks. The London Marathon is a bucket‑list moment — a day you’ll never forget — and we’d love you to enjoy every mile as part of Team Claire House.

How to enter

1. Apply for a Claire House charity place

Complete the application form and upload a 60‑second video telling us why you want to run for Claire House. Charity places are extremely limited, and your video helps us shortlist applicants when demand is high.

We will be confirming our team early summer time!

2. Already secured your own place?

Fantastic! Let us know you’re running and want to support Claire House. There’s no set minimum — simply raise what you can.

What you’ll receive

Once you’re on the team, we’ll send you a full Fundraising Pack, including your Claire House running top to wear with pride, water bottle, sponsorship forms and information about the difference you’ll be making.

Our Events Team will be by your side from your first training run to the finish line on The Mall — supporting you every step of the way.
