Why? There seems to be a prevalent theme among health professionals that a distance runner need NOT do more than, say, 5 miles/day and all kinds of other bullshit. Some of them try to suggest to competitive runners who've been injured that they should only run 4-5 days/wk from now on. It's frustrating as sh*t when they offer training advice. Why Don't they understand that you cant be good at running without more running than that? It seems like most of them only understand and can relate to the training for sports like baseball/basketball/football/hockey/volleyball, etc?
