VO2max and Peak Power Training Goals
5 min read
When threshold work stops moving FTP, use a short VO2max or peak-power block — 30-30s, 5x5s, sprints — then recover. Wearables decide if the interval day survives.

If your Power goal is peak power (watts at 5–30 seconds) or the FTP number has stalled, the limiter may be VO2max or neuromuscular speed, not more sweet spot. ChatGPT loves 5×5 forever. Connected to Garmin, Strava, Whoop, and intervals.icu, the question is whether today’s recovery can absorb 3–5 minute repeats — is the veto. Pair this with as sequential blocks, not the same week.
Polarized vs threshold distribution in endurance athletes
FTP-anchored zones used in structured cycling work
VO2max work (roughly 105–120% FTP, 3–8 min or 30-30s) raises the ceiling that FTP sits under. Peak/sprint work (Z7, very short) is a different success metric: target watts at a duration. Crits often need both repeatability and VO2; see crit repeatability. Hill-climb events need VO2 plus threshold, not only sprints.
Do not set peak-power and a 120 km fondo as equal primaries. The long ride will lose.
Amateur VO2 templates exist because longer VO2 diets create junk fatigue. Two VO2 days per week, endurance elsewhere, then a recovery week. Seiler still wants ~80% of time easy.
If 5×5s break down, shorter 30-30s or 4×8 at a hair lower intensity can be the better match to the limiter. Completing the set beats collecting DNF intervals.

Neuromuscular work wants short sessions, long recoveries, and no heavy legs from yesterday’s threshold. Put sprints on the freshest weekday. Whoop strain from a group ride is a reason to swap, not to “also sprint.”
Strength work can support peak power; it also costs legs. Adaptive plans and strength is the adjacent problem.
FTP retest after a VO2 block if FTP was the goal. Peak-power retest is a short effort on a known stretch or trainer. Do not judge a sprint goal with a 20-minute test.
Then either return to threshold density or switch the primary goal to Event if a date is close.
Three-week VO2 or peak-power specialty after a threshold base.
Save a Power goal for VO2 or peak watts, connect Whoop or Garmin, and let the next session survive only if recovery allows it.
