Lots of folks when racing an enduro will carry nothing but a gel and their goggles. When they get a puncture, f*ck them, they chose to go fast and light, keep begging matey!
the NN organisers will send you a minimum kit list closer to the time, with crazy essentials like waterproof, spare tube and water.
Basically you’ll want to to take everything you would for an ordinary 40 km loop away from the car, remove a few non-essentials, then add plus some cash for the pizza guys in the middle of the forest!
If someone is honestly stuck I’d obviously help them out. But far too often I’ll see people riding a race loop without the bare essentials…. gotta say, that’s the choice you made, don’t expect everyone else to be carrying your spares for you!
