Week 6 This is an easier week, so your body can absorb the training.
Week 7 A new 4-week cycle starts, focused on race-specific work at your race effort. Race-specific training: sessions at your race effort.
Week 14 Taper: less running, same intensity, so you start the race fresh.

Hill reps build strength and running form with less impact than speedwork.
Coach's note
Find a steady hill. Jog or walk back down to recover.

About these paces
Your coach sets your paces from your current fitness: a recent race, or your usual easy pace to start. Each race or 5K time trial updates them, and so do imported runs that show you're fitter.
What matters in 16 weeks
Respect the first month
The opening weeks aren't filler. They make the peak long runs possible.
Practice fuel before the peak
Test long-run fueling early enough to change it, not on race day.
Keep marathon pace honest
Race pace should feel controlled in blocks. If it wrecks the rest of the week, the target or the volume needs to change.
Questions before you start
Is 16 weeks enough for a marathon?
Often, if you already run regularly. When you set the date, your coach checks it against your running and long run, and tells you if the race comes too soon. The runner on this page, at 4 h a week with a 1 h 30 min long run, needs at least 9 weeks.
How many days a week should I run?
You choose, from two to six. Your coach spaces your runs through the week so you recover between them.
How long is the longest run for a marathon?
Your long run grows gradually from what you run now toward what a marathon needs, without big jumps from one week to the next. It peaks a few weeks before race day, then shortens in the taper so you start fresh.
When does marathon-pace work start?
In the weeks before the taper. On this page's road that's from week 6: a marathon-pace session most weeks, and long runs that finish at marathon pace.
What happens in the taper?
In the last weeks before your marathon you run less, at the same intensity, so you start the race fresh.
What happens after the 14 days?
Unless you subscribe, for $9.99 a month or $59.99 a year, your coach stops: no new weeks, logging, check-ins or reminders. You can still see your plan, past weeks and logged runs, and download or delete your data. We never asked for a card, so nothing is charged.
