Entry Fees

Early-bird entry online before 1 Feb
Advance entry online 1 Feb to 14 May
Manual entry after 14 May or on race-day*

*Subject to availability — we recommend that you enter in advance to avoid disappointment as the inaugural race held in 2016 was sold out.


Applications for transfer will be accepted until midnight on Thursday 17 May.


Should you need to withdraw from the race due to injury or illness, we will allow your entry to be deferred to the following year. Application for deferral is subject to an administration fee of £10 and should be made no later than midnight on Saturday 19 May.


Due to many of our costs being incurred up front, a refund would not be possible in the unfortunate event of cancellation. In the event that the race is cancelled or postponed we would offer free or discounted entry to a future race with the option to transfer or defer entry. The offer available would need to take into account costs incurred in organising the race and any additional costs required to organise a subsequent race.
