A paramedic who has spent the last few months running the course of the Northern Line is taking part in today’s London Marathon.

51 year old Stuart Crichton is Director of 999 Operations at London Ambulance Service.

He’s taking on the iconic 26-mile course to raise money for London Ambulance Charity.

To prepare for race day, Stuart trained by running 35km of the Northern line branch from High Barnet to Morden via Charing Cross.
