A Londoner is running the entire Underground network at street level to raise money for mental health charity Mind. Dave Abrams will follow all the lines on the tube in 25 separate runs as part of his marathon effort (actually the total distance is something like the equivalent of 20 marathons). His longest run will be the eastern half of the Central line, a 50km jog from Epping to Tottenham Court Road. You can track Dave’s journeys on Twitter via @undergroundrun. Or wait outside your local tube station with a cup of tepid Lucozade and a silly grin. Up to you.
