well, if you're gonna run outside in the winter, then I suggest
you get a pair of dedicated cold weather runners, or at least those
without fancy gel cushion gimmicks and stuff, the most basic ones
will do, but do get some breathable clothes though, warm sweat
inside and the cold air outside reads like a recipe for pneumonia
doesn't it ? ...
and go slow at first and build up your lungs, cold air in your
lungs and passages is not a good thing ... first time I jogged
outside in winter I came home bleeding from my nostrils because of
the icy air ... bod needs some time to get used to it ...
good luck ... and look out for the ice patches eh ...
