Depending on where you go, you'll be on snow for three to six months a year. Make sure to find out about the ski trails. Besides ski conditions you should think about dry-land training, because you will be doing a lot of that too. All of these factors can make training either enjoyable or a headache. Different schools have different team structure.
Some teams train together on a daily basis.
Other teams don't train together at all, and simply get together for road trips. The amount of coaching you'll receive varies a lot from school to school. Some schools have training plans that they expect you to follow, and at other schools, the coaches let athletes follow their own training programs. There are advantages and disadvantages to both styles and you need to decide what's best for you. Find out what team structure and coaching style is used at the schools that interest you.
