Here's Islay running. 3rd run was 9.03 seconds, 90 metres.
Islay is normally fastest on her first run. the speed will go slower and slower as she continues. The reason is not really her stamina, but more like her concentration wares off. Even when playing ball, for her 3 throws is like enough, so same with the lure-coursing. But still, she looks so excited when chasing, so lure-coursing sure is a great sport for Islay!
