Бегущим в гору. Руководство по тренировкам для трейлраннеров и скайраннеров

The book offers detailed strategies for mountain athletes—I'm curious what motivated the emphasis on altitude and terrain considerations.

The routines seem intense but effective; I wonder if they've been tested by non-professional climbers or runners seeking safe progress.

The mix of strength and cardio is compelling, but I'm interested in what guided the selection of specific drills for skiing endurance.
