The Olympic legend is set to retire on Thursday. Here is his cycling career tracked by the size of his monolithic thighs.
The BMX years – 1984-early 90s
Thighs: Scrawny and teenage, yet still strong enough to fell a tree
Medals: Silver – team sprint
Thighs: Getting there. Imagine a Brontomerus leaving adolescence.
Medals: Gold – 1km track time trial
Thighs: Increasingly log-like. Not quite in The Wrong Trousers territory yet.
Medals: Gold – team sprint, keirin, sprint
Thighs: Peak thigh – bulbous, elephantine Doric columns of power.
Medals: Gold – team sprint, keirin
Thighs: Like a decommissioned anti-aircraft gun, still fatally powerful.
