Seth James DeMoor’s video “Running Endurance Gains for PRs, this is What has Worked for me” has practical strategies worth a look. We’ve pulled the key takeaways so you can run a workout right away. Watch the full video for the deeper reasoning.

Key points:

  • Spend the first 8 weeks building an aerobic base with easy to steady-paced running (Zone 2-3).
  • Capillary density and aerobic capacity tend to step up once you’re comfortable with runs over 2 hours.
  • Add a weekly tempo session of 60-75 minutes (extend to 90 minutes if training for a marathon) at the lower end of Zone 4, where effort feels hard but sustainable.
  • When possible, include a 30-45 minute sustained hill effort (up to 60 minutes) to build leg strength and aerobic power. Run uphill only, skip the downhill.
  • Stick with it: 5 days of 20-30 minute jogging or a weekly volume of 40-80 miles keeps injury risk down and mileage consistent.

Workout example:

  1. Base run: 90-120 minutes at a steady, comfortable pace (Zone 2-3).
  2. Tempo run: 60-75 minutes (or 90 minutes for marathon training) at low Zone 4, comfortably hard.
  3. Hill session (optional): pick a hill and hold a moderate uphill effort for 30-45 minutes (up to 60), no recovery jogs downhill.

Try these workouts and dial in your paces using heart-rate zones in the Pacing app.
