Free marathon training plan
26.2 miles (42.2 km) · grounded in published sports science · free, no account needed.
The marathon is the one that demands respect. 26.2 miles is built over months of patient, mostly-easy mileage and a long run that climbs steadily toward race fitness. The biggest marathon mistakes are doing too much too soon and skipping the taper — a good plan protects you from both.
How long does a Marathon plan take?
Crawl2Sprint builds your plan back from your real race date and enforces a sensible minimum of about 12 weeks for the Marathon, inserting cutback weeks and around three weeks of taper. You'll want a running base before starting a marathon block — ideally comfortable with a 6–8 mile run. The builder scales the build to your experience, but the marathon rewards consistency over heroics more than any other distance.
What a Crawl2Sprint Marathon plan includes
- Gradual mileage built the way the injury research suggests, with regular cutback weeks. See the research →
- Mostly-easy running — about 80% easy, 20% hard (the polarized split). See the research →
- A right-sized long run (peaking around 16–20 miles for this distance), grown steadily. See the research →
- A proper taper — around three weeks of reduced volume so you arrive fresh. See the research →
- A day-by-day calendar anchored to your race, with each session linked to the study behind it.
What a typical week looks like
A typical marathon week is built around the long run, which climbs (with cutback weeks) toward a peak before the taper. Most weekday running is easy; a single quality session supplies the sharpening. Rest and recovery are non-negotiable.
How many weeks to train for a marathon?
Most plans run 12 to 20 weeks on top of an existing base. The build needs time to raise your long run safely and bank the aerobic volume the distance requires. The builder won't compress a marathon into an unsafe timeline.
Can a beginner train for a marathon?
It's ambitious but doable with a base and enough time. The plan emphasizes gradual progression and the long run; if you're starting from zero, a 5K or half first is the wiser on-ramp — and the plan will tell you when your timeline is tight.
