Kelsey leads the last few laps, does all the work getting past runners while Amaris sits behind her drafting. Then on the home stretch with the finish line in sight and Chmiel clearly spent from all that work, Amaris suddenly kicks it into high gear and passes Chmiel for the win.
Chmiel seemed really surprised to see her teammate go by her, then after the race it looks like Amaris is kinda freaking out, like she realized what she did, goes over to Chmiel and apologizes.
perhaps much ado about nothing, but interesting.
(also, watch at 16:55 when Amaris almost gets run over by lapped runners)
