Marathon Training Plan
Train for your marathon with structure, progression, and intelligence
PRYSM generates a personalized marathon program that evolves with your fitness. Volume management, fatigue tracking, and pace guidance — automatically recalibrated across your full 12 to 20-week block.
26.2 miles don't get prepared with a static plan.
A marathon block spans months. During that time, your fitness evolves, your schedule changes, and life happens. A fixed plan can't account for any of that. PRYSM can. Every session you log feeds the engine that recalibrates what comes next — so you arrive at the start line in the best possible shape, whatever the road looked like getting there.
How PRYSM prepares your marathon
Define your marathon goal
Target time, race date, current fitness level, weekly availability. PRYSM builds a realistic plan from your actual capabilities — not an assumed baseline.
Your 12 to 20-week program
Structured, progressive, periodized. Long runs, quality sessions, recovery weeks — all calibrated to your profile and adjusted throughout the block.
The engine adapts continuously
Every logged session refines the next. Strong week or tough stretch — PRYSM adjusts to maintain the optimal trajectory toward your race.

Why an adaptive plan changes everything for marathon
Long-cycle preparation done right
A marathon takes months. PRYSM manages week-by-week progression to prevent the load errors that typically lead to injury in long training blocks.
Intelligent volume management
Mileage increases follow progressive overload principles. The engine never gives you more volume than your body can currently absorb and recover from.
Periodization and peak timing
Your fitness peak is planned for race day. The 2 to 3-week taper is adjusted dynamically based on your actual form going into the final stretch.
Recovery and real-life flexibility
After a heavy week or a minor setback, PRYSM reorganizes your upcoming sessions rather than simply skipping what you missed.
