We use the estimated completion time you provided at entry to assign you to a wave with runners of a similar pace. On 3rd February, we sent a reminder email to all participants, giving them the opportunity to update their details before the cut-off later in the month.

It's a complex job to allocate start times for 35,000 participants and this has to be done with time to create the bib numbers and start the distribution process.

If you are part of a group that wishes to run together, you may drop back to a later wave within your group but cannot move forward.

Start Times can be found on our dedicated website page.

Entries for 2025 have now Sold Out. You can join the waiting list for our Official Charity places here - if a place becomes available you will be contacted by the charity directly. Alternatively, you can see a full list of our Associate Charities here. You can also register to receive updates to the 2026 event here and we'll be in touch when entries become available.

If you’re no longer able to join us on 27th April, check out this page for further information on our policy.

We publish all emails sent to participants on this page and if you have unsubscribed, you can resubscribe there too.
