WHO THIS IS FOR
IS THIS YOU?
The rider choosing a model
You've got enough hours to train properly and want to know which approach to build on.
The time-crunched amateur
You have 4–6 hours a week and wonder if sweet spot is the efficient choice.
THE ROADMAN VIEW
The Roadman view
This gets framed as a war, and it isn't. Polarised and sweet spot answer different questions. Polarised asks 'what produces the most durable fitness over a season?' and the answer, from Seiler's research and the World Tour coaches Anthony has interviewed, is the 80/20 split — mostly easy, occasionally very hard, almost nothing in the middle.
Sweet spot asks a narrower question: 'what produces the most fitness per hour when hours are scarce?' For a time-crunched amateur with four hours a week and an event in eight, a focused sweet-spot block is a defensible, efficient choice. The trap is that sweet spot feels good — productive, repeatable — so riders never leave it. Run year-round, it becomes exactly the grey-zone riding that stalls progress.
The Roadman view: build your year polarised, with a big easy base and a small dose of properly hard work, then use a short sweet-spot block to sharpen before a target event. Pick the tool for the question you're actually asking, and don't let the comfortable one quietly take over your whole calendar.
EXPERT EVIDENCE
WHAT THE EXPERTS SAY
- Professor Stephen SeilerExercise physiologist, polarised-training researcher
The 80/20 distribution is the most consistently supported pattern across elite endurance sport. The danger zone for amateurs is the moderate intensity in the middle — productive-feeling, but it accumulates fatigue without the adaptation of either truly easy or truly hard work.

Elite programmes are overwhelmingly polarised in their distribution. The amateur lesson isn't the volume — it's protecting the easy days and saving real intensity for the sessions designed to hurt.

PRACTICAL APPLICATION
DO THIS WEEK
Default to polarised if you have the hours
Train more than ~6 hours a week? Build it polarised: most rides genuinely easy, two sessions properly hard (one threshold, one VO2max), nothing parked in the middle.
Use sweet spot in short, deliberate blocks
Time-crunched or sharpening for an event? Run a 3–6 week sweet-spot block (2×20 min at 88–92% FTP) for efficient fitness, then return to a polarised base.
Police the grey zone either way
Whichever model you pick, check that your easy rides are actually easy. The failure mode for both approaches is the same: everything creeping toward moderate.
COMMON MISTAKES
WHAT CYCLISTS GET WRONG
MISTAKELiving in sweet spot all year because it feels productive.
FIXUse it in short blocks. Year-round sweet spot becomes grey-zone training and stalls most riders.
MISTAKEDoing 'polarised' but riding the easy days too hard.
FIXPolarised only works if the easy is truly easy. Half-polarised is just grey-zone with extra steps.
MISTAKETreating it as a permanent identity choice.
FIXThey're tools for different questions. Build polarised, sharpen with sweet spot near events.
