Following the structure and guidance in Scott Johnston & Steve House’s books Training for the New Alpinism and Training for the Uphill Athlete, I’ve focused over the past year on consistently accruing hours of work below my aerobic threshold (AeT). The past six months, I’ve averaged just about five hours per week, with more regularity than in prior years. Overall, my workload is at a 250 hours per year pace.

These hours have been very skewed towards low-intensity aerobic. Excluding strength training, I’ve spent 97% of my training time over the past year at or below my aerobic threshold (AeT). [1]
