Tempo Zones Train Your Lactate Threshold

Tempo Zones Train Your Lactate Threshold

The Tempo and Hard Effort intervals target your lactate threshold—the ceiling where your body can still clear lactic acid as fast as it produces it. Sustained output at this intensity forces your slow-twitch fibers and cardiovascular system to become more efficient, directly translating to faster sustained road speeds.

Why Cycling Economy Beats Raw Power

Why Cycling Economy Beats Raw Power

Road cycling rewards metabolic efficiency over peak wattage—your ability to sustain aerobic output across rolling terrain without accumulating fatigue debt. The progressive intensity structure here mirrors the demands of group rides and solo breakaways, where pacing discipline separates riders who finish strong from those who crack.

The 6-Minute Warm-Up Is Non-Negotiable

The 6-Minute Warm-Up Is Non-Negotiable

The Easy-to-Moderate Spin progression primes your cardiovascular output and lubricates hip and knee joints before threshold work begins—skipping it spikes injury risk and blunts interval quality. To personalize this session, anchor your Hard Effort to a perceived exertion of 8/10 or a specific power zone, then track how many sessions pass before that effort starts feeling like a 7.
