American swim queen Katie Ledecky said watching records tumble at the world championships inspired her to win a fourth straight 800m gold Saturday despite an illness that threatened to derail her. Ledecky, 22, withdrew from her 1,500m title defence and 200m heat earlier in the week in Gwangju and feared an early exit from Saturday's 800m final after a return of the mystery bug that has plagued her for days.
"I got to the pool this morning to warm up and felt a little nauseous again which wasn't great," she said. "I had a brief moment of doubt there but pulled it together and made it happen today. "Last night after watching all the fast swimming I said (to my coach) I so, so badly want to go have a good swim tomorrow. Just watching those records tumble... really fired me up," she added.
Five-time Olympic champion Ledecky was given a fright in the 800m by European champion Simona Quadarella but held off the Italian to win in 8:13.58 and capture a 15th world title. "Each swim has its own story," she said. "This one definitely has one that I'll be telling for a while," added Ledecky, revealing that she had spent seven hours in hospital on Tuesday after being struck by headaches and insomnia and experiencing an irregular pulse and elevated heart rate. Ledecky, visibly emotional at the side of the pool, expressed a "sense of gratefulness" towards the family and coaches that had helped pep her up this week.
