Wanting a bigger long run and needing recoverable easy days often conflict. Skip the 5K base and jump mileage, and the plan becomes injury math. Assumes continuous easy running (ideally a recent 5K block); three runs/week, mostly easy. Tools: Pace Calculator, Zone 2 Calculator, Pace Chart, Race Predictor, VO2 Max Calculator.

Guardrails Before You Build

  • Easy days conversational; quality controlled, not all-out
  • Long run drives endurance — progress time gradually
  • Missed week → repeat it; two sick weeks → restart mid-plan, not peak week

Numeric scenario: Mid-plan long run ~55–60 min. If the last 15 min drifts >20–25 sec/km vs the first 15 at same effort (or HR +8–10 bpm at fixed pace), cut next long run 8–10 min and skip quality once — no catch-up intervals.

Expert Note

Gray-zone easy days are the usual reason long runs flatten in weeks 6–8.

Decision rule: if long-run form collapses or shin/Achilles pain alters gait, cut quality first and shorten the long run before touching the race date.

When Heat or Fatigue Wins

In heat, prioritize HR over pace. Missed long run → next long at 90% duration. Fourth run only after solid weeks, short and easy.

Practical Takeaway

Arrive able to run easy for the distance, then race with patience. Recover a few easy days before a repeat 10K or half build.

FAQ

Do I need a recent 5K first?

Strongly preferred. If continuous running still feels shaky, finish a beginner 5K block before this plan.
