Course Conditions
After last year’s canceled swim, this year saw a “regular” Ironman in Busselton. The race was quick as usual (adjustment of 13:26), but there have been quicker conditions before and overall pretty much in line with the course rating of 16:39. It’s been mainly the bike that has been fast, as evidenced by a new bike record by Cam Wurf (his 4:07 was just a minute quicker than Luke McKenzie’s time from 2015) and Caroline Steffen missing Mareen Hufe’s bike record from 2016 by just three minutes even with a slow flat in the last miles before T2. Caroline’s overall time was good enough for a female course record, with an 8:49 she improved Mel Hauschildt’s time from 2016 by five minutes.

Kona Qualifying
IM Western Australia had one base slot for each gender plus two unassigned slots. Based on my understanding of the assignment process and the number of athletes starting the race (8 females and 13 males), one slot should go to each gender. This means that both of the top two finishers in each gender get a Kona slot, and Terenzo Bozzone, Cameron Wurf, Caroline Steffen and Barbara Riveros have secured their Kona 2019 start.
