Jackson overcame a 3:02 deficit after the swim with a by-far women's-best bike split and women’s second-fastest run to finish in 3:57:20 with a 6:37 margin of victory over Jennifer Spieldenner of the U.S. and 7:42 over 3rd place Svenja Thoes of Germany.

Jackson’s win continues a strong 2017 season which includes victories at Peru and Chattanooga 70.3s and a 4th at Oceanside 70.3.

Amberger opened a big lead with the fastest swim and bike splits, and then closed the deal with a 2nd-best run to finish in 3:35:07 with a 9:49 margin of victory over fellow Aussie Kieran Roche and 10:53 over 3rd-place finisher Jonathan Shearon of the U.S.

Amberger continues to ride high after a 2nd places at Dubai and Geelong 70.3s, a win at Jönköping 70.3 and a breakout win at the Asia-Pacific Ironman Championship at Cairns preceded his victory at Calgary.

While Amberger’s 3:35:07 and Jackson’s 3:57:20 finishing times appear to be record-threatening times for the distance, their 1:55:06 and 2:05:17 bike splits strongly suggest a short bike leg.

Women

Jennifer Spieldenner of the U.S. led the women’s swim wave in 22:45 which gave her a 1:54 lead on Christen Brown of the U.S., 1:59 on Jenny Fletcher of the U.S., 2:01 on Svenja Thoes of Germany and 3:02 over Jackson.

Jackson took care of all threats with a 2:05:17 bike split which was 6:17 faster than Sue Huse of the U.S., 6:44 better than Thoes and 7:15 better than Spieldenner. Starting the run with a 4:16 lead on Spieldenner, 6:15 on Thoes, 7:56 on Brown and 9:58 on Huse. Jackson finished with a women’s second-best 1:24:12 run which Huse bested by 14 seconds.
