Emergency personnel will also be stationed at key points along the course in the case that you need assistance.

Bike Recommendations:  Hardtail or full suspension cross country MTBs would be ideally suited to the course. The singletracks are not suitable for Cyclocross bikes. It can be very muddy on section of the course, depending on the weather..some riders have used very fat MTB tires but most opt for tires in the 2.0 range with tread patterns matched to the weather/surface moisture conditions.
