The Flatline Base Builder, a Aerobic cycling workout from Thanh Vo

Workout library · Stimulus

Aerobic cycling workouts

Sustained aerobic power below VO2 max: the engine between endurance and threshold.

The stimulus

Aerobic, explained

What it is

Intervals and blocks at 80–100% of critical power, longer than VO2 max efforts and harder than tempo, often with torque or cadence work built in. Step-downs, long tempo-to-threshold progressions and torque blocks belong here.

Why it matters

Why it matters

This is where aerobic capacity is converted into usable power: the ability to hold a high fraction of VO2 max for long periods. It is the stimulus behind time trialling, long climbs and the last hour of a road race.

If you ride it

If you ride it

These sessions are long and demanding but not maximal. Pacing is the skill: the target is even power across the block, and the last minutes should feel hard but possible.

If you coach it

If you coach it

Aerobic sessions are the bridge in a block: enough intensity to hold the ceiling gained from VO2 work, enough volume to keep the base. Watch the intensity score in Vekta; these sessions should score high on volume and moderate on intensity.

In Vekta

Personalised to CP in Vekta, with the intensity graph showing where the session bites. Afterwards the session is classified by its dominant stimulus and compared with the athlete's previous aerobic sessions.

Common questions

Is aerobic the same as endurance?

What cadence?

How does this differ from sweet spot?
