PARIS — Sifan Hassan says she must be addicted to the pain.

How else can you explain hatching a “crazy” dream to race the Olympic 5,000m, 10,000m and marathon within a week — and then medalling in all of them?

It was a warm Sunday in Paris — less than 38 hours after she’d won bronze in the 10,000m, six days after running to bronze in the 5,000m — when Hassan’s screaming legs found another gear in the final metres of her favoured race. She outkicked marathon world record holder Tigst Assefa of Ethiopia to break the tape in an Olympic-record time of two hours, 22 minutes, 55 seconds.
