Cardio endurance

Make steady work feel more available.

Explore pacing, aerobic volume, intervals and recovery through the practical realities of training after 35.

The architecture of an endurance week

A durable week usually contains more easy work than hard work, with enough variation to support adaptation without making every session a test. Easy sessions build tolerance and rhythm. A controlled harder session can challenge the ability to sustain a higher output. Rest and ordinary movement help those signals settle.

Easy aerobic work

Keep the effort conversational enough to repeat. Duration can grow in small steps when joints, sleep and schedule agree.

Threshold awareness

Use breathing and pace to locate work that is demanding but organised, rather than chasing an impressive finish.

Short intervals

Brief efforts can support economy and power when they are separated by generous recovery and preceded by preparation.

Pacing is a skill.

The first minutes of a session can feel deceptively easy. A restrained opening creates room to observe breathing, stride and muscular tension before making a decision. This is especially useful in hot, humid conditions, where external temperature alters the internal cost of a familiar pace.

Record the route, weather, sleep and perceived effort. The notes often explain more than a single personal record.

Signals to log after a session

  1. How quickly did breathing settle during the first ten minutes?
  2. Did the chosen pace remain technically tidy near the end?
  3. Was the next morning ordinary, heavy or unexpectedly fresh?
  4. Could the same session fit the coming week without borrowing energy from work and family?
“Endurance is partly the ability to distribute attention over time.”
