Double threshold with me. No carbon.
.
I don’t have anything against carbon. In fact I love it for workouts. But I just had a bunch of shoes that needed testing so I figured I’d take them for workouts where I might normally reach for a racing shoe. Each of the shoes did great. I think the Endorphin Speed 5 is better for big workouts than the Hyperion 3, as I found myself landing literally and figuratively a bit flat footed for a lot of my reps. It just got really easy to run sloppy in the Hyperion 3, but it very well could have been that my body is very tired from the last couple weeks of high mileage.
