How it works
Three steps to your race-ready plan
STEP 01
Set your race
Choose your distance — 5K, 10K, half, marathon, or a custom distance. Enter your race date and we'll build the plan back from race day.
STEP 02
Pick your days
Select how many days per week you can train and your current fitness level. The plan adapts to your schedule — 3 days or 6 days.
STEP 03
Get your plan
Every session includes a full structure — exact intervals, distances, heart rate zones, and coaching tips. Export to .ics for your calendar.
The four phases
Every plan follows proven periodisation principles
Base
Easy aerobic runs build your cardiovascular foundation. Volume increases gradually — max 10% per week.
Build
Tempo runs and threshold sessions are introduced. Your lactate threshold rises and race-pace effort becomes sustainable.
Peak
Highest volume and intensity. Interval sessions sharpen speed. Long run hits its maximum. Real fitness is forged here.
Taper
Volume drops 30–50%. Short sharpeners maintain fitness. Legs freshen up. Arrive to race day fully rested.
How the plans are built
Based on established exercise science — not guesswork
VDOT PACING
Jack Daniels' VDOT
Your training paces are calculated using the VDOT methodology developed by Dr. Jack Daniels, exercise physiologist and author of Daniels' Running Formula. Enter a recent race time and the system derives your current aerobic capacity, then prescribes exact paces for easy, tempo, and interval sessions. The same system is used by elite coaches worldwide.
PERIODISATION
Classical periodisation
The Base → Build → Peak → Taper structure follows periodisation theory — the principle that training stress should be varied in a planned cycle to maximise adaptation and arrive at race day in peak condition. Originally formalised in Soviet sports science in the 1950s, it's now the foundation of virtually every serious endurance training programme, including those by Pete Pfitzinger and Hal Higdon.
INJURY PREVENTION
The 10% rule
Weekly training volume never increases by more than 10% over the previous week — a guideline supported by research on overuse injury incidence in runners. Every fourth week is a planned recovery week at 70% of normal volume, allowing the body to absorb the training load before the next build cycle.
