What your power curve says about you: sprinter, puncheur or diesel?

Line up every best effort you've ever done — hardest 5 seconds, hardest minute, hardest 5, 20, 60 minutes — and join the dots. That line is your power-duration curve, and it's one of the most honest documents in cycling. It falls steeply at first (nobody sprints for long) and flattens toward the right, and its exact shape — where it towers, where it sags — is a fingerprint. It says what kind of rider you are more reliably than any amount of self-image does.

Reading the curve: four durations, four questions

You don't need the whole curve to profile yourself — four points sketch it. Each duration stresses a different physiological system, and each asks the body a different question:

Bar lengths are illustrative of a typical curve's shape, not anyone's actual watts — a sprinter's chart and a diesel's chart bend very differently, which is the whole point.

The comparison that matters isn't your raw watts against someone else's — it's each duration relative to your own FTP. Every rider's curve falls from left to right; yours is interesting where it falls slower or faster than typical. A 1-minute power at 250% of FTP is a weapon whatever your FTP is; a 5-minute power barely above your 20-minute power says your ceiling, not your engine, is the limiter.

The four archetypes

Riders cluster into recognisable shapes. Most of us are a blend, and the boundaries are fuzzy — but you'll almost certainly see yourself in one of these more than the others:

A note on the climber: it's the one archetype defined less by curve shape than by the denominator. Divide a diesel's sustained watts by 58 kg instead of 80 and you get a different racer entirely. If your raw numbers underwhelm you but you float past people uphill, check your W/kg before your self-esteem.

Train the weakness, or double down on the strength?

Once the curve has told you what you are, you face the classic coaching fork — and the honest answer is it depends on what's costing you.

Train the weakness when it's the thing eliminating you from the results you want. A sprinter who gets dropped before the finish never gets to sprint; that rider's limiter is aerobic, and threshold work — however unglamorous — buys more wins than another watt of peak power. Likewise a diesel who loses every group ride at the same 30-second kicker can transform their riding with a modest anaerobic top-up. Weakness training also has the better economics: an undertrained system improves fast, while your strength is already near its ceiling.

Double down on the strength when it's genuinely what wins for you and events can be chosen to suit it. Racing rewards being exceptional at one thing far more than being decent at everything — nobody attacks with the pack's most well-rounded rider. If your diesel wins you time trials and breakaways, making it even bigger is a better use of a season than dragging a hopeless sprint from terrible to merely bad. The practical rule: fix the weakness that ends your race; sharpen the strength that wins it. Off-season is for the first, race season for the second.

See your own curve — no test required

The best part is that your curve already exists — it's sitting in your ride history. Every hard start, chased wheel and full-gas climb you've ever recorded contains a best effort at some duration. Moveee's power profile page assembles the curve from your rides automatically, marks your best efforts at every duration, and models your FTP from the shape — so you can see exactly where you tower and where you sag without booking a single test day. Connect your rides and have a look: most riders find the curve confirms what the club run already suspected about them.

And whichever shape you find — sprinter, puncheur, diesel or climber — remember it's a starting point, not a sentence. The curve describes the rider you've trained, not the only rider you can be.
