Recovery ‹what’s this?›
Very easy, conversational pace (<65% AeT) for active recovery.
Foundation ‹what’s this?›
Fundamental runs just below your aerobic threshold (AeT) to build your base safely.
Steady ‹what’s this?›
Comfortable endurance pace (≈75–85% VO₂ max) to improve aerobic capacity.
Tempo ‹what’s this?›
“Comfortably hard” sub-threshold effort – heavy but controlled breathing; sustain ~30–40 min.
Lactate Threshold ‹what’s this?›
Mike Scannell’s LT: pace where lactate production equals clearance (~4 mmol/L), held 20–60 min by elites.
Critical Velocity ‹what’s this?›
Tom “Tinman” Schwartz’s CV: highest constant aerobic pace—single words only; ~8–15 min.
5 K ‹what’s this?›
Estimated 5 000 m pace; typically ~95–98% VO₂ max.
3200 m ‹what’s this?›
Projected 3 200 m maximal-effort time.
1600 m ‹what’s this?›
Projected 1 600 m maximal-effort time.
800 m ‹what’s this?›
Projected 800 m maximal-effort time.
400 m ‹what’s this?›
Projected 400 m maximal-effort time.
