After a world textile best of 1:54.66 in the 200m free yesterday, Camille Muffat, of Nice and France, scorched a 4:02.97 victory in the 400m, leaving the fight behind her.
How Muffat arrived at her second best ofthe season after the 4:01.13 world textile best she clocked in March was simply staggering: out in 2:04, she came home in 1:58, all part of the learning curve on the way to coping with world champion and record holder Federica Pellegrini (ITA) and defending champion Rebecca Adlington (GBR) at London 2012.
The actual splits: 1:01.09; 2:04.43; 3:04.01 (3:34.13); 4:02.97.
The tussle for the minor spoils went to Barbara Jardin (CAN) in 4:09.46, 0.1sec ahead of Melanie Costa (ESP).
Muffat's consistency of speed this year is truly impressive:

Muffat is also scheduled to race at the Paris Open in early July.
South African World Cup winner of 2011, Chad Le Clos came close to his season best in the 200m butterfly when he kept Brazil's Kaio Almeida at bay with a 1:55.46 to 1:56.10 triumph.
Le Clos fell a touch shy of the 1:55.30 he clocked at Olympic trials back home in April, while Almeida has also gone faster this season, a 1:55.59 last weekend in Barcelona the target to beat. The only other man inside 2mins was Jordan Coelho (FRA), on 1:58.73.
Out in lane 8, Hanser Garcia, of Cuba, caused upset in the 100m freestyle with a 48.89 victory over former world champion Brent Hayden (CAN), 49.00, and Yannick Agnel (FRA), 49.02.
Garcia had only broken 49sec twice before, a 48.34 at Pan Ams last year a big step up from a best of 48.99 in the heats at Shanghai world titles.
His teammate Pedro Medel also triumphed today from an outside lane. Having arrived in Canet with a best time of 2:01.32 from the heats at the Beijing Olympic Games in 2008 as a 17-year-old, Medel goes to bed tonight with a first senior win in international global waters under his belt and a new best time for a target after a 2:00.34 victory from lane 1.
The pacemaking of the man in lane 2 doubtless helped: Ben Stasiulis, the Frenchman who helped to keep joint 100m world champion Jeremy Stravius out of the two-lapper at London 2012 when he finished second to the other joint world champion, Camille Lacourt, at French trials in March, was there all then way - and stopped the clock in his lane just 0.04sec adrift Medel's winning moment. Third place over the other side of centre was Russian Andrei Shabasov in 2:01.39.
