London Marathon – October 2021

This is one of world’s most iconic marathons with 10,000 incredible runners per year pounding the streets of London for good causes. With the 2020 marathon postponed due to coronavirus, the event will be back in 2021 bigger than ever!

We have a limited number of places available in the 2021 London Marathon. We ask all our successful applicants to raise a minimum of £2,000 for COSMIC and pay a registration fee of £50. Download an application form to apply.
