Outcome
Lactate threshold
Threshold is 'how fast you can go for a long time' — where most endurance races are decided.
What to do first
- • Add controlled tempo/cruise intervals once per week.
- • Keep easy days truly easy so threshold work stays high quality.
- • Progress duration before intensity.
