Coach Benson's Secret Workouts: Coachly Wisdom for Runners About Effort-Based Training

Review: updated look at effort-based training, meant for the self-coached athlete rather than the coach. It's dense but understandable, and really lets you work out your own training plan based on your own needs and abilities. There are bits which require putting in some time and concentration, without question, but there is a real payoff. Especially useful for older runners who need help keeping themselves uninjured.
