A group of 22 women came together after the first of seven laps on the bike, building a gap of 40 seconds by the time they finished lap two. Jackson rode comfortably in the pack, alongside fellow pre-race favourites Kirsten Sweetland (CAN) and Emmie Charayron (FRA).
Charayron was the first to make it through T2, but both Sweetland and Jackson were right on her heels. By the end of the first of four run laps, Jackson was at the front with a 10-second advantage over Sweetland, as the pair continued to pull away from the rest of the field.
Jackson flew through the final kilometres, easily breaking away from Sweetland to stop the clock in 1:58:07.
"I've been focusing on this race all year long and was really hoping for a podium, so to come out here and win is a dream come true," Jackson said. "I always like to go out of transition hard to see what I can do and today I felt great for the whole run."
An ecstatic Sweetland crossed the line 52 seconds later to finish, posting the best finish of her season.
"I'm so proud of my finish today. It was a perfect way to end the season," Sweetland said. "This is the first time I've been healthy for the World Championships since 2006, so to come out and finish second today is amazing for me."
Charayron, last season's Junior World Champion, rounded out the podium in 1:59:19.
The Elite women will compete tomorrow, starting off at 2pm local time. Live coverage will be available on triathlon.org/tv
