The overall rhythm

16 weeks in three phases: build a base, raise volume, then taper. Each week has one long run, two easy runs, and one interval session.

💡 80% of your mileage should be at an easy pace. Slow down to last longer.

Key weeks

  • Weeks 1–6: settle weekly mileage at 25km
  • Weeks 7–12: push the long run to 16km
  • Weeks 13–16: taper while keeping cadence

Gear

A well-fitting pair of shoes matters more than anything: Nike Pegasus 41affiliate link.
