Fundraising Commitment
On offer of a place, participants are required to pay their £100 registration fee. If you have secured a Roald Dahl’s Marvellous Children’s Charity charity place, you agree to raise a minimum of £2,500. If you have your own place (ballot/club), we ask that you raise as much as possible.

- £1,000 (40%) by January 15th, 2027
If this milestone is not hit then as explained your place could be forfeited. This is so we have enough time to recruit another participant.

  • £2,500 (100%) by race day- 24th April 2027
Any corporate sponsorship or match funding must be agreed in advance with the Roald Dahl’s Marvellous Children’s Charity Challenge Events Team.
