@Kaldak Thanks for the tips, I'll look to try and incorporate bricks into my workouts.
@Polar Bear If I had to guess I would say I'm probably running completely wrong. I've never had any formal coaching/instruction. Have any specific resources on running form to share?
@ThunderHorse I'm focused right now on getting fit to take screening tests, so swims of 500-1500m and runs of 1.5-3 miles for time
@Devildoc Is running with a weight vest risky on your knees? Is there a specific technique you need to use or should I just run normally?
@Arf What would you say is a good goal to strive for for treading? An hour? With hands or without?
