Training notes

Make the plan fit the runner.

The long run carries more weight

With only three runs, long-run progression needs to be steady and recoverable.

Threshold beats random speed

Half marathon performance depends heavily on sustainable aerobic power, not all-out intervals every week.

Recovery is part of the plan

Fewer runs can still be too much if intensity and long-run jumps are not controlled.
