Double Olympic champion, Rebecca Adlington, who was also reported to be ill this morning, proved that she was made of sterner stuff as she collected the 800m freestyle title with a clear lead over South Africa's Wendy Trott and Australia's Melissa Gorman, with a time of 8:24.69 which did not quite set the pool ablaze.
In men's action, Brent Hayward (Canada) cracked the 48s code for the first time in the world this year — also marked by the total ban of racing suits — as he demolished the rest of the field in the 100m freestyle final.
Hayward, who was second fastest after former World record holder Eamon Sullivan (Australia) in this morning's semifinals, proved to be a blast as he scorched through the two laps and returned at 47.98s.
Reigning champion Simon Burnett (England) touched in at 48.54s, ahead of Sullivan (48.69s) to redeem some prestige and collect the silver.
South Africa's Chad Guy Le Clos pulled off a great win the 400m individual medley, to gain his second gold medal of the Games.
Desolate
The Indian camp was left desolate as Virdhawal Khade and Sandeep Sejwal failed to make it into the finals of the 100m butterfly and 50m breaststroke, both finishing ninth in the overall rankings of their respective races.
In Synchronised swimming, Canada expectedly had a field day as it collected the solo and duet titles, with maestro Marie Pier Boudreau-Cagnon leading her team right from the front.
Boudreau was a runaway winner of the solo title before she teamed up with Chloe Issac for a second gold.
