Inclement weather can be an issue .None of the above choices .Many people prefer the ease of conditioned air .It is easier to do some sports while outside .
Why is it important for athletes to spend time outdoors ?
Every other kind of sport had people outside ; hikers , bikers , boaters , rollerbladers , you name it . So where did the rock climbers go ? Now that there are indoor climbing walls , has everybody who likes to climb moved indoors ?
