Because most people only catch soundbites:

Doesn't sound like jogging to me:
Monday 10 miles (15km) at 1/2 effort over undulating course
Tuesday 15 miles (25km) at 1/4 effort over reasonably flat
Wednesday 12 miles (20km) at 1/2 effort over hilly course
Thursday 18 miles (30km) at 1/4 effort over reasonably flat
Friday 10 miles (15km) at 3/4 effort over flat course
Saturday 22 miles (35km) at 1/4 effort over reasonably flat
Sunday 15 miles (25km) at 1/4 effort over any type terrain
Look another "conditioning" program by Lydiards:
1. Conditioning (As long as possible) 2 week cycles.
Monday: Aerobic running 3/4 to 1 hour.
Tuesday: Aerobic running 1 to 1.5 hours.
Wednesday: Run hilly course 1/2 to 1 hour.
Thursday: Aerobic running 1 to 1.5 hours.
Friday: Jog 1/2 to 1 hour.
Saturday: Run hilly course 1/2 to 1 hour.
Sunday: Aerobic running 1.5 to 2 hours.
Monday: Run hilly course 1/2 to 1 hour.
Tuesday: Aerobic running 1 to 1.5 hours.
Wednesday: Time trial 3000 or 5000 meters.
Thursday: Aerobic running 1 to 1.5 hours.
Friday: Jog 1/2 to 1 hour.
Saturday: Relaxed striding of 4 to 8 times 200 meters.
Sunday: Aerobic running 2 hours or more.
People don't realize that Lydiard often contridicted himself from one moment to the next, or better put: he tweaked his program from day to day to deal with individual runners.
