Are there any mountain guides on /out/?

How did you prepare to meet entry requirements?

You have to provide a list of at least 35 routes which includes varied mountain routes, ski tours, technical climbs, and other experience carried out over a period of at least three years. During these climbs, the applicant must either have been the rope leader with full responsibility or have been doing alternative leads with shared responsibility.

Does one fill it with previous experience or is it better to start doing these routes as part of the preparation for future training?
