Recently we got a tapis roulant (treadmill) for my mother as the doc told her she should walk at least 3Km per day and she doesn't like the idea of going around like a drone for no reason (except at home I mean).
Of course I ended up giving it a try and I've the impression that running on it is harder than running on the street. I did a 10Km run at 10Km/h and I was really almost dead when finishing (no kidding I was counting the last minutes one by one and telling myself "you can do it.... c'mon! don't give up!").
Actually I'm used to run quite longer at about that speed so this puzzles me... I've no idea if it's the missing of the fresh air flowing in the front of you or if it's being *forced* to keep a constant speed. Anyway I like not having to worry about bad streets any I felt my shoulder and back ok even if I noticed my left knee "feeling" the run a bit at the end anyway.
What was also shocking was the price we paid for it. In the company I work for I think that we wouldn't be able to get such a thing out on the market for five times the price we paid to have it delivered to hour house. Ok the huge numbers they produce in China, ok for the really low labor cost over there... but still there is something that looks wrong to me in that price.
