Registration for Cobblemonster 2019 on Sunday 14th April is open.

Registration is now close

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 our first event in 2009.

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

Donate online to Evelina London

The generosity of our punters has meant over £30,000 has been raised since 2009.
