Endurance Training

Build the aerobic base that supports all other cycling fitness. Long rides, zone 2 work, and progressive volume building.

Key takeaways

  • Spend most easy rides in zone 2 at a conversational effort.
  • Keep heart rate at 60 to 75 percent of max or power at 55 to 75 percent of FTP.
  • Grow weekly volume by no more than 10 percent.
  • The longest ride should not exceed 40 percent of weekly volume.
  • Follow the 80/20 split between low and high intensity for 8 weeks to see the effect.

Endurance is the foundation of all cycling performance. Without a strong aerobic base, higher-intensity efforts fatigue you prematurely and recovery takes longer. Building endurance requires patience and consistent volume.

Zone 2 training

Zone 2 intensity feels conversational. You can speak in full sentences. Heart rate sits at 60 to 75 percent of maximum. Power output is 55 to 75 percent of FTP. This feels easy, and that is the point. Zone 2 develops mitochondrial density and fat oxidation.

Most recreational cyclists ride too hard on easy days and too easy on hard days. Discipline yourself to ride genuinely easy on endurance days, even if it feels slow.

Progressive volume

  • Increase weekly hours by no more than 10 percent per week.
  • Every 3rd or 4th week, reduce volume by 30 to 40 percent for recovery.
  • The longest ride of the week should not exceed 40 percent of total weekly volume.
  • Add duration before intensity. Build to your target hours before adding hard sessions.

Mental strategies

Long easy rides can feel tedious. Listen to podcasts, ride with friends, explore new routes, or focus on pedaling technique. The hours in zone 2 accumulate and produce noticeable improvements in your ability to sustain effort over months.

Recovery

Adaptation happens during rest, not during training. Sleep, nutrition timing, active recovery, and knowing when to take a day off.
