WHO THIS IS FOR
IS THIS YOU?
The time-crunched rider with 5-8 hours a week
You can't fit long, separate easy and hard sessions, so you need a zone that delivers solid adaptation without needing 90 minutes of dedicated recovery afterward.
The rider building a base of sustainable intensity
You want a structured way to add quality to your week without the all-out demands of true threshold or VO2max intervals.
THE ROADMAN VIEW
The Roadman view
Sweet spot gets treated online as either a miracle zone or a trap, and the truth sits in between. It's an efficiency tool. You get most of the physiological benefit of threshold work with meaningfully less fatigue cost, which lets you do more of it across a week. For a rider training 6 hours who can't afford two full recovery days after a threshold session, that trade is really useful.
The problem starts when sweet spot becomes the only intensity a rider ever does. Stephen Seiler's research on polarised distribution is a caution here — an entire training week built from sweet spot sessions, without properly easy days either side, quietly becomes a grey-zone plan. You're never hard enough to force the top-end adaptations and never easy enough to properly recover.
Used correctly, sweet spot is a tool for a specific problem: limited hours. It is not a replacement for either properly easy riding or properly hard threshold and VO2max work when you have the time to do them properly.
EXPERT EVIDENCE
WHAT THE EXPERTS SAY
- Dr Andrew CogganExercise physiologist, co-developer of the power-based training zone model
Sweet spot occupies the zone just below threshold where a rider can accumulate substantially more total training stress per session than at true threshold intensity, without the same multi-day recovery cost — useful for riders who need efficiency more than peak stimulus.
- Professor Stephen SeilerExercise physiologist, polarised-training researcher
The risk with any moderately hard training zone is that it becomes the default for every session. Athletes who train exclusively in a sweet-spot-type zone, without truly easy days, tend to plateau faster than those who polarise their intensity.

PRACTICAL APPLICATION
DO THIS WEEK
Structure sessions as repeated 10-20 minute blocks
A typical session is 3×15 minutes at 88–92% FTP with 5 minutes easy between efforts. Build up total time in zone gradually across several weeks rather than jumping straight to long blocks.
Cap sweet spot to two or three sessions a week
Even though it's more repeatable than threshold work, sweet spot still accumulates fatigue. Two to three sessions a week with properly easy riding on the other days is a sustainable structure for most amateurs.
Keep your easy days actually easy
Sweet spot only works as intended if your non-interval days are low intensity. If every ride sits at a moderate effort, you lose the recovery that lets the sweet spot sessions produce adaptation.
COMMON MISTAKES
WHAT CYCLISTS GET WRONG
MISTAKEMaking every training session sweet spot because it feels productive.
FIXBalance sweet spot sessions with properly easy riding. A week entirely at 85-90% FTP is a fatigue plan, not a training plan.
MISTAKETreating sweet spot as interchangeable with threshold training.
FIXSweet spot and threshold produce overlapping but distinct adaptations. If your goal is maximum FTP gain and you have recovery capacity to spare, true threshold work at 95-105% FTP is more direct.
MISTAKEStarting with sessions too long for your current fitness.
FIXBuild up total sweet spot volume gradually — start with 20-30 minutes total and progress over several weeks rather than attempting a 60-minute session in week one.
