Training for a Marathon: Heart Rate Zone Strategy
Marathon training demands a smart approach to heart rate zones.
A typical marathon training plan heavily utilizes:
  • Zone 2 (Aerobic Base): Majority of your mileage for endurance and fat adaptation.
  • Zone 3 (Tempo): To improve lactate threshold and race pace.
  • Zone 4 (Threshold): For shorter intervals to boost speed endurance.
"Consistency in zones builds confidence on race day."
