Raise your VO2 max over sixteen structured weeks with this top end season builder for riders training 7 to 8 hours a week. Progressive time near maximal oxygen uptake, from early VO2 primers into 4x4 and 5x4 intervals, 30/30 and 40/20 microbursts, Ronnestad 30/15 short intervals, decreasing rest ladders and descending clusters, lifts the ceiling that decides hard finishes and steep climbs. Every ride is Zwift and indoor trainer compatible with power targets in percent of FTP, so it scales precisely to you.

WHO IT IS FOR. Cyclists who want a bigger engine and more repeatable high end power across a full base to peak season, from committed riders with a structured base to experienced racers chasing a new VO2 max. You need around 7 to 8 hours a week and a smart trainer or power meter.

HOW IT PROGRESSES. Two base blocks lay an aerobic foundation and introduce VO2 work, a build block adds Ronnestad short intervals and decreasing rest ladders, a three week peak maximises time at VO2max with clusters and descending ladders, and a taper sharpens into a retest. FTP tests on day one and the final day bookend the plan so you measure a full season of gains.

WHAT MAKES IT DIFFERENT. Every ride carries a full six section description, a pre activity fuelling and pacing cue, and one verified academic reference matched to what the ride trains. No two quality sessions repeat across sixteen weeks, and the endurance rides undulate rather than sit flat. Durability work places VO2 efforts late in long rides so your top end survives fatigue.

WHAT TO EXPECT EACH WEEK. Two quality days, an undulating endurance ride, a long weekend ride with sweet spot or VO2 work, a recovery spin, and a rest day, with recovery weeks at four, eight and twelve and a taper into the final test. Weekly hours sit at 7 to 8 in loading weeks and near 5 and a half in recovery and taper weeks.
