I ran a mile today as a warm-up for sparring class. I was able to breath the entire time! (and for the eight laps up and down three flights of stairs.)
If these new meds keep working, who knows, I might be up to try a half-marathon by the end of the season. No marathons for me, though. I need more speed if I'm going to try that. I can't run for five hours straight. I'm not like the man who runs all day.
