You'll start at Woolwich Royal Artillery Barracks and head through Charlton, along the Thames Path and around the Greenwich Peninsula.

The full marathon looped route heads through Charlton, along the Thames Path to Greenwich and the O2, Old Royal Naval College and the fabulous Cutty Sark, then onwards through central London. It’s then past the Tower of London, and on to the Olympic Park, before returning to Woolwich via the foot tunnel.
