Can I enter and Fundraise for another Charity on your event?
A lot of time and effort is put into organising the BBMC to further the aims of our Charity. We would ask participants to not fundraise for other charities on our event or turn up on the day wearing clothing fundraising for other Charities. If you wish to support other charities it might be worth speaking with them first as they may run similar events that you can also take part in.
