The definition of "high" or "low" volume training can vary from athlete to athlete. While I consider our training volume to be low compared to what some athletes do when training for an endurance triathlon event, it may also be seen as "high" volume compared to what other athletes do for long workouts. Since much of our weekly volume occurs from frequent training sessions (instead of two "long" workouts each week), I'd say that we have the right mix of intensity, frequency and volume to encourage training adaptations without risking injury or burnout. Certainly, this was years in the making with lots of trial and error and many athlete case studies to learn from. Last year I was interviewed for a Triathlete magazine article on this topic of high/low volume training. I really enjoyed providing my insights on this topic for I feel many endurance triathletes adhere to haphazard training which includes high volume workouts. weekend after weekend...
