Jump in the saddle and rack up some late summer miles riding between 25 historic castles on a 120-mile, 200-mile or 330-mile virtual cycle challenge for Pilgrims Hospices.

Ride your favourite local routes and track your progress, and everyone else's, along the virtual route map. Simply ride when and how often you can throughout September and see if you can reach the Tower of London before the month is up. You can even include the miles you do on an indoor training bike.
