Threshold Cycling Intervals
Threshold cycling intervals train sustainable hard power—often 95–105% of FTP—for eight to twenty minutes to raise lactate clearance and race pace.
Threshold cycling intervals sit at or just below functional threshold power—often 95–105% of FTP—for efforts from eight to twenty minutes, sometimes stacked as 2×20 or 3×12. They raise the power you can hold for forty to sixty minutes.
Balance with zone 2 volume; too much threshold crowds recovery. Fuel longer threshold blocks with carbs.
Common questions
-
How is threshold different from sweet spot?
Sweet spot sits slightly below threshold—hard but more repeatable volume; true threshold is closer to one-hour race power and more taxing.
-
How often can I do threshold intervals?
Most riders tolerate one to two threshold-focused sessions weekly during build phases, not year-round without easy weeks.
