Who this plan is for
An experienced runner training 5+ days a week and chasing a specific time goal.
Advanced plans run two quality sessions in most weeks — threshold, VO₂ max, and race-pace work — supported by higher weekly volume and sharper peak-week sessions, all inside the same safety guardrails: max two hard days, no back-to-back quality, and mandatory recovery weeks.
What you'll work on
- ✓ Progressively build weekly volume and long-run endurance
- ✓ Develop marathon pace with race-specific workouts
- ✓ Protect against injury with recovery weeks and the 10% rule
- ✓ Taper intelligently to arrive on the start line fresh
