Which is better: Ramp Test or 20-Minute Test?

CoachingCOMPARISON

RAMP TEST VS 20-MINUTE TEST

QUICK VERDICT

The 20-minute test is more accurate for most riders but harder to pace. The ramp test is easier to execute and more repeatable but can overestimate FTP for riders with strong anaerobic capacity.

SIDE BY SIDE

FEATURE	RAMP TEST	20-MINUTE TEST
Accuracy	Good (±3-5%)	Better (±2-3%)
Pacing difficulty	None (progressive)	High (must hold steady)
Duration	~20 min total	~45 min with warm-up
Repeatability	High	Moderate (pacing varies)
Anaerobic bias	Can overestimate	Less biased
Mental difficulty	Moderate	Very high

CHOOSE RAMP TEST IF

✓New to FTP testing
✓Riders who struggle with pacing
✓Frequent retesting (every 4-6 weeks)
✓Indoor training platforms

CHOOSE 20-MINUTE TEST IF

✓Experienced riders who can pace well
✓More accurate zone calculation
✓Riders training for TTs or steady-state events
✓When absolute accuracy matters
