I think it took me around 20 minutes. Probably not a very good time, though i have no idea what other people do. I walked at a normal pace with the sandbag, while changing carry styles occasionally. I would like to go to a 400m track and try the workout. I just went outside my house and went around the block, which i think is pretty close. I used a 60lb sandbag, definitely could have gone heavier on the carries, not sure how much heavier on the cleans.
