The weekly volume per week will gradually move up to 12-14. You should already be consistently training 8-12 hours per week before starting this plan and ideally you should have completed some Olympic distance races in the past season
This plan is based on an annual volume of 500 hours per year, an average of 10 hours per week. It will build to 12+ with recovery weeks at around 8 hours per week.
