Mountain biking is full of challenges and there is always a risk
involved. Be aware of the consequences when taking risks.
That is to
say if you're attempting a tricky section and not sure if you can make
it, what happens if you fall? If you are just going to fall into bushes
then it might be a risk worth taking.
If you're going to fall down a steep
gulley, it's a risk not worth taking. Sounds obvious but these split
decisions have to be made constantly.
Another thing worth considering. Helicopters cannot fly in low
visibilty and will not be able to come out to rescue you in the event
of an accident. In bad weather, take fewer risks and try to stay near
to a 4X4 trail where the emergency services can get a vehicle to you.
Wear a helmet.
Always carry a mobile phone in case of emergency and make yourself
aware of the relevant telephone numbers for emergency services (in
Italy and Switzerland too if necessary).
Always carry a first aid kit and be aware of how to use it.
