I'm not sure yet, I was pretty knackered afterwards today. I'd rather stay at 2 miles till it gets a little easier before increasing my distance.Sounds like improvement to me....time to add a bit to your runs?
I have suffered with hay fever in the past so that could be it, the trailway I run down is lined with trees and god knows how many bushes, plants etc.....ah ha, now you are pacing
Runny nose I don't know. Do you have hayfever as you could be breathing in pollen.
Grumbly belly I get if I haven't eaten enough to cover the miles. As I run on an empty stomach this is quite often.
Swollen fingers, do you run with rigid shoulders? I get a numb right hand if I don't think to keep my shoulder lose.
