Greater London

London's running scene is dominated by flat, fast courses: the Thames Path stretches 184km through the city, the London Marathon follows a largely riverside route through central London, and Regent's Park and Hyde Park offer traffic-free loops. Cyclists have more variety — VeloPark GP and SOUTHERN GRIT (110km) showcase the city's velodrome and longer gravel routes, while harder terrain emerges south of the Thames toward the North Downs around 30km away, or north into the Chilterns for sustained climbs above 200m elevation.
