2018-06-04 Rider down, Farringdon Road (came off on raised kerb)

Max Hotopf, 60, was thrown from his bike after colliding with the painted ridge which separates cyclists from vehicles in Farringdon Road. He said the ridge, about 10cm high, looked like a regular white line marking which he could cross.

Tthat should obviously read '10mm'. 10cm would be fairly grotesque. But yes, upstands like this can be treacherous and are a known cause of injury especially in older riders (usually when attempting to cross lowered kerbs diagonally). Heal up soon, Max.
