If you need hill training, why not try it on a mountain bike?
Dark & White are offering the following on 3rd August 2011...
A 2 hour evening Bike O run along slightly different lines to the traditional score/route choice style event. Starting from a central point, there are 6 routes to follow all of which go uphill. Each uphill has control points (SPORTident boxes) in ascending order of value i.e. the higher you go the greater the points!
