Sweet spot is a coaching term commonly used for cycling at 88–94% of FTP. It overlaps upper tempo and lower threshold in common power models; it is not a separate physiological threshold or a guaranteed route to a fixed percentage gain.
This page is the Roadman learning path for the subject. Start with the evidence-reviewed definition, then choose the comparison, calculator or adjacent training guide that matches your decision.
Start with the canonical guide
Read Sweet Spot Training for Cycling: 88–94% FTP Explained for:
- what the power band means and where the convention comes from;
- why FTP test method changes the practical target;
- what research does—and does not—show about benefits and fatigue;
- repeatable session examples and progression boundaries;
- weekly-dose decisions without a universal frequency rule; and
- masters guidance based on individual response rather than age alone.
The guide is the single Roadman owner for “sweet spot training”, “sweet spot cycling” and definition-led questions. Other resources below answer narrower jobs rather than repeating it.
Choose the right comparison
- Sweet spot vs Zone 2 compares sustained sub-threshold work with lower-intensity volume.
- Sweet spot vs threshold separates the overlapping power bands and their practical uses.
- Polarised vs sweet spot compares a whole training-intensity distribution with one type of session.
- Sweet spot vs threshold vs polarised provides a wider decision framework.
Calculate and build the session
Use the sweet spot calculator to display 88–94% of a current FTP. The FTP Zone Calculator shows the surrounding power bands, and the interval builder turns a chosen target into a structured session.
The calculated watts are a starting point. Keep the FTP test method attached to the value, begin conservatively and review pacing, RPE, technique and the next normal training day before progressing.
Understand the neighbouring systems
- FTP training zones explains why zone names and anchors are not interchangeable.
- Cycling threshold intervals covers sustained work nearer FTP.
- Cycling VO2max intervals covers above-threshold formats and evidence.
- Cycling periodisation places the session inside a longer plan.
- Zone 2 training covers lower-intensity volume and its boundaries.
The Roadman rule
Do not choose sweet spot because the workout feels productive or because a plan labels it optimal. Choose it when controlled sub-threshold work serves the rider's current goal, fits the complete week and remains repeatable.
There is no universal two- or three-session requirement, no mandatory four-to-eight-week block and no evidence-backed “90% of the benefit” formula. The useful dose is the one the cyclist can execute, absorb and connect to the event.
