I like that every rider needs to bring an observer. brilliant.
In that case we only need 30 riders :-), which is properly all we will get anyway.
There will be fuel every 10/15km or so after a section. Fuel will included in the entry and properly 50:1 premix with some clean super for 4st and the guys who prefer to mix their on the spot.
Fire risk is going to be virtually nil, as it will be during our wet winter.
Fire extinguishers will be compulsory anyway and you must finish with it or take penalty points (ie if you loose it).
Marking, it appears that we have found a biodegradable spray paint which apparently will fade and be gone in approx 6 weeks outdoors. This makes marking a breeze as we can essentially mark 95% of the course without arrows and pegs. Nice and easy to clean up too. I'm awaiting info from a forestry guy about the stuff.
The event will be in Hawke's Bay, New Zealand.
