Guinness World Records

If you're running the TCS London Marathon, why not attempt a world record while you're at it?

Guinness World Records is once again collaborating with us to give participants the chance to attempt to break a world record of their choosing. 

All you need to do is register your world record attempt before Marathon Day on the Guinness World Records site.

If successful, your attempt will be verified at the Finish Line.

Please note that you must already have secured a place to apply for a record. Places in the event are not available via Guinness World Records.
