Registration for Cobblemonster 2023, Sunday the 9th of April is now open!

To sign-up, just fill in our entry form here.

Entry is free but we recommend a donation to our official charity Evelina London Children’s Hospital. Our guideline donation is £15 and this has remained the same since the very first event in 2009.

If you’re taking part it will help a lot if you donate upfront, although you can give us cash on the day too.

The generosity of our punters has meant over £30,000 has been raised since 2009. In the words of the immortal Brixton Cycles Workers Cooperative, we salute you.
