Course Conditions
This year conditions were calm with almost no wind but also hot temperatures on the run. This made the race (adjustment of 16.25) about three minutes quicker than last year but very much in line of what is typical for the course (course rating of 16:38). Most of that quick time comes from the bike leg (adjustment of 16 minutes).
The conditions helped to set a number of new course records: Female winner Teresa Adam improved on the bike course record set by Mareen Hufe in 2016 (4:41:32) and the overall record set last year by Caroline Steffen (8:49:45). Alistair Brownlee was faster than the 2016 course record by Terenzo Bozzone (7:51:26) and the 2007 run course record by Robert Thomas (2:43:48).
