The registration fee for the marathon is £25 which you pay online upon completing the registration form. The registration fee is non-refundable.

We ask everyone to pledge to raise £250 to support people living with cancer. Click on Your Hike in the navigation bar where we have lots of useful information and resources to help you get started. 

The deadline to register for the Wye Valley Mighty Hike is midnight on Friday 26 August or when the event sells out.

It is possible to transfer between the full marathon and half marathon distances. Please know that if you request to transfer to the lower distance the £5 difference in registration fees will not be refunded.

Transferring between distances is not possible if the request is made less than 2 weeks before the event as registration will be closed or if the event is sold out.

If you wish to change from the half marathon to the full marathon, we will ask you to pay the £5 difference in registration fees.

If the event is full, and you would like to take part, you should fill out your details by clicking through at the top of this page, and you will be added to the waiting list.

The waiting list works on a first come first serve basis, and will offer out places when a participant has to drop out for any reason. When you get to the top of the list and a place becomes available for you, you will be emailed with an invite to register. You must use the link in this email to register within 7 days, or the link will expire. If you no longer wish to take part, you can decline the invite and the place will be offered to the next person on the waiting list.

We absolutely appreciate supporters are motivated to join our Mighty Hikes because of very personal connections to Macmillan. With this in mind, we recommend you join the waiting list as soon as possible, which will give you the best chance of securing a place on the event. We believe this is the fairest way to guarantee everyone has an equal chance of being invited to join the event.

Therefore, when choosing your start time, please select an earlier wave if you consider yourself a slower walker and a later wave if you consider yourself a faster walker.
