Due to the off-road nature of the course, we highly recommend that you use a mountain bike. In addition, to provide a level playing field for all participants, only those using a mountain bike may win prizes. Anyone using a hybrid or cyclocross bike will not be allowed to podium if they finish in the top 3. The course is unsuitable for road bikes or slick tyres.
If you do not have a mountain bike and would like to use either a hybrid or cyclocross bike then, before you enter, we highly recommend looking at the video footage of last years' bike course to see for yourself the conditions of the route - specifically the off-road sections here and here.
After looking at the footage (or trying the bike route yourself) you would still like to enter then please remember that you do so at your own risk and that you will not be able to podium if you finish in the top 3.
