Entries for 2026 are now open. Once the initial places are sold, a waiting list will be in operation.
Exceptions to this are volunteers who have earned a guaranteed free entry in advance.

Runners may also enter the event as part of the 100 mile Grand Slam. To take part in the Slam, runners can enter each event individually, or buy a Grand Slam ticket which gets you entry to all four 100 Mile Slam events. Information on the Grand Slam, and how to enter can be found by clicking here.
Cancellation, Refund, Deferral & Transfer Policy
Runners who withdraw up to 4 weeks prior to race day (2359 GMT Friday 28 days prior) are eligible for either a refund, minus a 30% admin fee, or a deferral to 2027, minus a 15% admin fee.
Withdrawals within four weeks of race day will not be eligible for any refund and cannot be deferred.
To defer, runners must contact us via email by clicking here. Your 2026 place will then be cancelled and any refund protection (if taken out) will be voided. You will be invited to sign up for the 2027 event, prior to general entries open. The cost due at that point is 15% of your 2026 fee plus any price difference for 2027. If you choose not to sign up at that stage or withdraw prior to race day, no refund will be issued.
To withdraw please find your entry here, login and click on my entries (if you have Xcover please see below first). You can then cancel your own entry. Your card will automatically be refunded the 70% fee up to 4 weeks before race day. This can take up to 10 working days to reach your account. Within four weeks of race day, you can still cancel your entry, but without any refund.
Exception to this is ONLY for pregnancy/ postpartum and in which case you must notify us by email here of your pregnancy no later than 4 weeks prior to race day to be eligible for a 100% refund. You must acknowledge that you understand and agree to this policy during the registration process.
