The course and race map
Although the actual course may change slightly from time to time as mountain conditions alter the route, the following maps should give you a good idea of what to expect.
Drink stations, loos and gear check locations
There are drink stations at all the major check-points which serve water, leppin, bananas and generally oranges, museli bars and jellybeans. All these are marked onthe race map along with loo points. Note that the Rainbow Reach toilet is across a short bridge off the main track - approx 100m return.
Kepler in profile
Put simply, the full Kepler goes up sharply, down steeply then tailing off to a long slow incline. The steepest and potentially most treacherous part are the long stairs down from the Hanging Valley shelter. These are in 6 sections and around 200 steps in total.
The Kepler Track is entirely within the Fiordland National park and is overseen by the Department of Conservation. For their description of this great walk and up-to-date information follow this link.
