Key Points

  • Fartlek means “speed play”: alternate fast efforts with easy jogs to boost both speed and aerobic endurance.
  • In marathon training, Matthew follows an 80/20 rule – 80 % easy miles, 20 % dedicated speed work.
  • The workout is designed to raise and lower heart rate repeatedly, teaching you to handle pace changes during a race.
  • Focus on effort, not the clock; keep the fast intervals hard but sustainable, then recover fully.

Workout Example

  1. Warm‑up: 2 mi easy run + a few 100‑m open striders.
  2. Main set: 10 × (2 min fast + 2 min easy jog)
    • Fast pace: roughly 6:10–6:40 min/mi (adjust to your target marathon pace).
    • Easy jog: light recovery pace.
    • Total main set time ≈ 40 min.
  3. Cool‑down: 2 mi easy jog.

Closing Note
