Are women better ultra-endurance athletes than men?
Through thunderstorms, scorching heat and icy rain, Fiona Kolbinger cycled 2,485 miles (3,999km) in a little more than 10 days over some of Europe's most demanding terrain.
In doing so, the German cyclist became the first woman to win the Transcontinental Race this week. That in itself was remarkable: it was the first time she had formally competed in an ultra-cycling event.
But what was all the more remarkable was the fact she finished the brutal journey from Bulgaria to France a full 10 hours ahead of her closest opponent.
