Hot topics

Unable to take part?

  • If you have a place in the 2023 mass event and are unable to take part, you’ll need to withdraw your entry. You can do this via your participant dashboard, which you can access from your confirmation email or an email we sent on Friday 24 February. You’ll then have until 23:59 on Saturday 22 April to withdraw.
  • Once you've withdrawn, you may have the chance to defer your place – please see this page for further information. Please note that you’ll still need to pay for your deferred TCS London Marathon place.

Still need help?

If the above hot topics do not answer your question, our FAQs page is a great place to find instant answers to some of our other most common enquiries.
