London Marathon 2025

London Marathon 2025

Registration fee: £50 Minimum sponsorship: £2,200
27th April 2025 London


The London Marathon needs no introduction. As the most iconic marathon in the world, it attracts runners of all abilities who get to soak in the incredible sights of London and the electrifying atmosphere of the crowd.

The London Marathon is our biggest fundraiser of the year. Each charity runner is expected to raise £2,200 for the charity and run 26.2 miles, which is no easy task! This is months of fundraising, organising events, packing bags, creating raffles and hosting bake sales ON TOP OF training!

However, we’re on hand to help with fundraising ideas and support. Our team will also be there on the day, both cheering our runners on from the sidelines and at the finish line to applaud all your hard work.

The support from the crowds was amazing, and we got to see the Roy Castle Lung Cancer Foundation team cheering us on twice on the route as they were stationed at two milestone areas! They were screaming my name as I passed by, it certainly kept me going!

  • It is the UK’s biggest cancer killer, with over 36,000 dying from lung cancer every year. It kills more people than breast, prostate and pancreatic cancer combined, and more women than breast and ovarian cancer combined.
  • It is our mission to ensure everyone diagnosed with lung cancer can live well with the disease for as long as possible.
