Run 39:55 [3] 5.85 mi (6:49 / mi) +84m 6:32 / mi
slept:4.1 shoes: Under Armour HOVR Sonic 3
Tried to shorten stride as was Under Armour's suggestion.
Anyone know why I can only take extremely shallow breaths and feel tightness on my chest/lungs resulting in cramps when I run downhill? I'm not running at an unreasonable pace (nearly same as flat), my chest is upright, my form isn't significantly different, I don't even feel the exertion that I feel when running flat/uphill (it's not like I'm pushing myself, I'm letting gravity do a lot of the work). I just can't breath that well when running downhill and it hurts my pace cause I get mad cramps.
As far as I can remember this has been a thing since at least freshman year of college (two years ago).
