Big Black Mountains Challenge 2025
We’re back with the ever-popular BBMC and its choice of three routes (20km, 31km, and 49km) in the heart of the glorious Black Mountains for walkers and runners of all ages and abilities! Come rain or shine, it’s always a fun day and places go fast.
We have now frozen entries to prepare for the event. If you wish to change route this can be done on the day. We can sadly no longer offer cancellations or refunds as per our T&C’s.
If you have any questions drop us an E-Mail : bbmc@longtownmrt.org.uk or WhatsApp : 07356 073390
Numbers are strictly limited due to permissions with landowners and to limit the effects on the environment, landscape and safety considerations.
We would love to sneak you in but if we did it to everyone we wouldn't be able to cope!
Forget to order your T-Shirt or Hoodie, or want to change the route distance? Simply go back to the registration email and use the Amend Entry function at the bottom to make any changes.




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.
