295lb, 5ft9in newbie here. First Tri in 6 days.
Swim, cake
Bike, no big deal
Run... uh.. walking counts right?
Ok, now you know where I'm at...
I find that when I start running, besides the obvious SPIKE in hear rate after running even a short distance, I have trouble breathing. Not like panting, but in getting a GOOD DEEEEEEEP BREATH like I have trained to do in riding, elleptical, swimming (ok, so I'm still working on that).
Can't get that good "diaphramatic"? breath in and it's driving me nuts.
Maybe it's just all my muscle and fat jiggling around that it's physically not possible but I never say never so...
I'm asking!
