Alpine Challenge

Alpine Challenge Course Notes for Alpine Skyrun 100 Mile Participants
and Support Crews

This event will challenge many runners/walkers and they will need to be prepared for all weather conditions. Detailed below are basic course notes for each stage of the event. These should not be used in place of map/compass/GPS to navigate the course. They are a guide only and address some of the more problematic parts of the course and give some idea as to track conditions.

The Alpine Challenge is a mutual support event, it is not a race in the traditional sense; participants must offer assistance to others in distress.

The 100 mile course includes 6 major climbs, each of approximately 1,000 m, that take a cumulative toll and takes place in an exposed Alpine environment that can be subject to sudden and severe changes in weather. Hot sunny days as well as rain, fog, high winds, sleet and snow can occur during April. Hypothermia and hyperthermia are serious risks and runners must be prepared for any weather conditions.

By entering participants are confirming their ability to map read and navigate in difficult conditions.

This is the Relive video of Brendan Davies' 2021 April run.


Support: All runners are responsible for arranging their own support crews who are able to meet them at pre-designated support stops. Due to the high DNF rate in the 100 mile event, runners need to have arrangements in place to transport them back to Falls Creek in the event of a withdrawal. This usually happens at either Loch Car park or Harrietville on the night section of the run.

The organisers are able to provide limited support if needed for interstate/overseas runners.
