Robin Pomery (USA) and Katie Thomas (USA) exited the waters of Lake Monona together with Linsey Corbin (USA) heading into transition in third, +3:21 back of the lead pair.
Corbin dominated the bike early and managed to take the lead at 20 miles into the bike. Building upon her lead at each check point on the strength of the fastest bike split on the day, Corbin would enjoy advantages of over twelve minutes on Thomas and a nearing 30 minutes on Jeannie Hansen at the conclusion of the 112 miles.
That would be as close as Corbin's rivals would manage to get to the multiple IRONMAN champion, as Corbin went on to claim the 2018 IRONMAN Wisconsin title in a winning course record time of 9:12:39, with gaps of well over 30 minutes on Hansen and Thomas who finished second and third.
