B8073
The B8073 around the northern edge of Mull is a gruelling but spectacular single-track gauntlet. With rough surfacing and a relentless density of sharp corners, it forces you to drop your pace and work the pedals with deliberate care. It is a harsh road that tests your suspension and your stamina, but the engagement is absolute.
The climb out from Calgary Bay gets incredibly slick after a rain shower, often catching out rear-wheel-drive cars on the steepest hairpins.
