Spirig overcame a minute deficit after the swim with a second-fastest bike split and the best run of the day, to finish in 2:07:15 with a 59 seconds margin of victory over Annamaria Mazzetti of Italy and 2:01 over 3rd-place finisher Ainhoa Murua of Spain.
Spirig, the 2012 Olympic champion, seems fully back on track for a defense of her Olympic title at Rio after taking time off to have a baby in 2013 and winning a few long course events. Spirig successfully defended her 2014 European Championship title and followed up her early season with 3rd at WTS Cape Town and a recent victory at the European Games in Baku.
Jodie Stimpson, the 2014 Commonwealth Games champion and runner-up in the 2013 World Triathlon Series, suffered a puncture and dropped from contention to a 9th place finish.
