Charity places

Due to high demand, we've sold out of charity places for the Royal Parks Half Marathon 2025.

However, you can join our reserve list and we will contact you if a place becomes available. You will not need to pay your registration fee until we invite you to sign up with a charity place. If places do become available, they will be on a first come, first served basis.

Ballot places

If you already have a ballot place, you can sign up to join Team Blood Cancer UK at the Royal Parks Half Marathon and run to beat blood cancer.
