Sifan Hassan stopped twice and was almost run over by a TV motorbike en route to the most dramatic win in London Marathon history.
The Dutch star, a two-distance Olympic track champion, had never before run a marathon and forgot to strap her troublesome hip before taking to the start line.
She had come straight off a month of fasting during Ramadan, had no experience of running on asphalt and zero experience of drinking fluids during a road race.
