Do the entire ride under your own steam. No catching a lift.
You must follow 100% of the course. If you need to deviate
from the course (for example, to buy supplies to get your bike
fixed), then you must rejoin the course at the point where you
left it.
You must carry all your own gear.
The only services you can use are those available to everyone.
That is, you can use shops and other commercial organisations
along the way, but you can't have your mum bring you a spare
tube, or pop in at a friend's place for dinner.
Trail angels are very welcome, but must give support to
everyone who passes by. They can't be selective.
You must use a Spot tracker connected to the Mega Grind
tracking page.
