Marathon in 3h30: 16-week plan

16 weeks, 5 runs a week, to run a marathon in 3h30 (4:59/km). Written for a VMA around 15.5 km/h. Week 1 is about 41 km; the biggest week reaches 76 km and the longest run lasts 2h40. Every session has its targets: a share of VMA for easy runs and intervals, your goal pace for race-pace work.

Week-by-week schedule

Every session with its targets. Each one carries a step-by-step workout that goes to your watch once the plan is imported.

Targets are a share of VMA or your goal pace. Once the plan is imported, OpenAthlete works them out from the VMA in your profile, and your Garmin, COROS or Suunto watch shows your own paces.

Base

Easy volume, short fast reps and strides. The long run grows a little each week. Week 4 is lighter, to absorb the work.

Paces for this goal

Finishing in 3h30 means 4:59 per kilometre on average. The plan writes every target as a share of VMA or as this goal pace. If your recent races say otherwise, check your VMA or a recent result before you start.
