The Etape Caledonia is an 81 mile cycle challenge taking place on traffic-free roads in the stunning scenery of Highland Perthshire. The event on 16h May 2010 is now sold out and will feature a whole variety of individuals between the ages of 18 and 80. To ensure that the roads are reopened to the schedule agreed with the authorities, participants will need to maintain an average speed of 13-14mph around the course. This gives at least 6h 15mins to reach the finishing line within the closure window. Even if you are unable to meet this average you can continue on open roads and complete the full circuit.
