Downloadable routes for the both the Hare and Tortoise routes can be found here
Routes are in gpx format and can be imported into appropriate cycling apps. I use the iphone app Cyclemeter or Bike Hub
Whilst the intention is for each group to ride together, it is a good idea to have the routes saved on your phone, in case you get separated from the group.
The total ride has been split into 5 routes. First 3 routes are before lunch. Second 2 routes are after lunch.
