A Sub-40 10K is a serious performance goal.

To break 40 minutes, you need to average approximately 4:00 min/km — and that requires much more than simply running harder.

This structured plan is designed to develop the aerobic fitness, threshold speed, running economy and race-specific endurance needed to move toward that goal.

Inside you’ll get:

✅ 8-week and 12-week training options
✅ Full day-by-day schedule
✅ Easy runs, long runs, threshold sessions & intervals
✅ Race-specific pace work
✅ Detailed training pace ranges
✅ Heart-rate guidance
✅ Weekly mileage and training-time summaries
✅ Race-day pacing strategy
✅ Pre-run warm-up routine

This plan is intended for experienced runners who already train consistently and have a solid running base.

Every session has a purpose. Easy days support recovery. Quality sessions build performance. Consistency connects everything together.

4:00/km. 10K. One goal: Sub-40.
