02 · Training Approach

How to reach this goal

Reaching sub 50 min is not about more effort, but more precision. The training prescription derived from your Runlevel puts every session at the right intensity zone.

Running 10K under 50 minutes requires solid aerobic capacity and speed endurance. A common training combination is T (threshold) runs and I (VO2 max) intervals to raise both the speed ceiling and lactate tolerance, with E (easy) recovery runs to maintain weekly volume. Some coaches suggest that 10K sub-50 intervals can start with 5×1 km at T pace, progressively building interval training volume to steadily improve results. The pace table below lists precise paces for each intensity.
