The event was won by Sweden’s Mikaela Norman (32:50), who sits fourth overall, with New Zealand’s Jamie Greene finishing third (38:53) to leave her second overall.

“Once we got rid of our vests, I felt really good and knew I could push it harder and try to get ahead of Sam,” Norman told The Morning Chalk Up.

“Towards the end of the race I had no idea where she was behind me, so I just kept running like she was right behind me all the way to the end.”

Briggs recorded her third second-placed finish (34:41) in three events to open up a 20-point lead at the top of the women’s standings.

“I saw the distance between us and the energy it would take to catch her, but I didn’t know how [Mikaela] she was feeling, so I didn’t want to risk it,” Briggs told The Morning Chalk Up. “I knew I had second secure, so I just kept it nice and easy to the finish.”
