The Snaefell Mountain Course is no oval, no purpose-built track ringed by gravel traps and run-off. It is the everyday road network of the Isle of Man, swept clean of traffic for a fortnight in late spring, and a rider who leaves the throttle pinned through every one of those bends covers the lap in just over sixteen minutes. Peter Hickman's outright record stands at 16 minutes 36.115 seconds, an average of 136.358 mph through hedgerows, stone walls, village high streets, and the broad open shoulder of a mountain.

Birkin's Bend at Kirk Michael remembers Archie Birkin, who in a 1927 practice session swerved to avoid a fish-van on an open road and struck a wall; from 1928 onward practice was held only on closed roads...

The Verandah was cut deeper into the hillside in the early 1970s after Gilberto Parlotti died there in heavy rain. The Quarterbridge has been reshaped repe...
