I did it for the first time last year, what an experience!!
Tickets should be available until the last minute, i dont think it even sold out last year.
The two mates i did it with have done it before, so we ended up practicing the main course a few times and the quali a couple of times.
On our first day we went over to Les 2 Alps. It was shockingly bad. Some of the worst trails i have ever ridden. But we were only there for a day and just rode the ‘main’ ones. there could be some hidden treats.
But the Mega is such an awesome experience. Hearing the starting music still makes my hair stand up on end now!
Go forth and enjoy! 🙂
