25-Minute Intermediate Cycling Time Trial
A structured bike time trial with warm-up, a steady 20-minute effort, and a short cool-down.
Warm-Up
Gradually raise heart rate and prepare legs for sustained effort.
Main Set
Sustained time trial effort.
Cool-Down
Bring heart rate down and flush the legs.
Pacing the Anaerobic Threshold Line
Hard Cycling and the Time Trial effort target your lactate threshold—the intensity where lactate production meets clearance. Moderate Cycling primes your aerobic engine before you push into that zone, so your cardiovascular system isn't playing catch-up when watts matter most.
20 Minutes: The TT Athlete's Crucible
A 20-minute maximal effort is the gold standard for estimating functional threshold power, demanding sustained recruitment of slow-twitch fibers while your fast-twitch units buffer accumulating lactate. Pacing discipline in the first 5 minutes is the single biggest predictor of a strong finish.
Threshold Blocks Build Race-Ready Power
This session follows a classic threshold block structure—progressive intensity across warm-up, sustained overload in the main set, and active recovery to flush metabolite buildup. To personalize it, anchor your Hard Cycling effort to an RPE of 8/10 or 90–95% of your max heart rate and track how that ceiling shifts week over week.
