RE: Inhalation problems..
Boxer, yes. I have run on and off constantly, mainly because of my crippling shin splints. As of now i am running almost everyday, adding about 100 metres extra daily. The majority of my runs cover roadsides and hay fields.
It's amazing how much better it is running outdoors. On the treadmill, i have gone for 5 hours while watching t.v with no problems...outside i am winded in 30 minutes :(
