i would look to start in lez gets, started in morzine this year noone wanted to finish off by going to lez gets and coming back
start as early as possible as checkin can be slow and long wasting time when you could be on the bike
it can take a lot longer if you add on the little extra riding which is more fun than the motorway routes which can link the lifts
you will punture so the thickest tyres you can afford cannot belive the amount of people with their bikes upside down
its a good day out do not lose your lift pass as you get an extra day free on it
