Three teams left the juggler pretty close together......1) Brooke/Claire, 2) Conner/Jonathan, 3) Katie/Rachel. You can see them all running across the field at the same time in the episode. Conner/Jonathon took a direct route and crossed the creek in deeper water. Brooke/Claire and Katie/Rachel went out of the way to find shallow water to cross. When Conner/Jonathon step on the mat, you can see Brooke in the distant background. I would say it was 2/3 minutes between B/C and K/R.
