Hey slowtwitchers have a question to see if anyone else experiences this or knows any insight. Every distance event more than 4 hours I have a really hard time breathing. Like to the point where I can only go for like a quarter mile without stopping to walk and even at like a 10 minute pace. It had been consistent at mile 8 of either an Ironman or 70.3. Any insight?
To make it a little easier I’ll give some background. I have a 253 marathon to my time and have not ever had this issue with marathons. My ftp is 330 and kept my Ironman bikes around 235 (which I feel is pretty conservative so I can run well) nutrition wise I’ve taken in around 300-400 calories an hour on the bike (played with it over the last few Ironman) . Just did Santa Rosa yesterday and was 8th overall coming off the bike and until about mile 6 and then the breathing thing came up and had to proceed to a run/walk as I couldn’t go more than 1/4 mile without having trouble breathing.
Has anyone else experienced this??
It definitely doesn't fit the classic presentation of exercise-induced bronchoconstriction (immediate to within 20 minutes). Does it feel like your chest won't expand or the breaths you're taking just aren't effective? Is there tightening of your airways (i.e., inspiratory or expiratory symptoms). When you go to the doctor for this, the more detailed you can be about your symptoms and what's happening in the environment, the more likely they'll be able to figure out what the problem is.
