I had a race on Saturday and I did a hill climb event on Tuesday. After one heat in the hill climb I noticed I had an itch/scratchy feeling in the back of my throat that made my eyes water and cough. It sort of went away and I finished the remaining heats.
I was doing some intervals today and I noticed I had the same feeling for a bit so I reduced my effort slightly and finished the next 25km no problem.
Its very hot and dry here but sometimes humid. It been suggested to me that I should breathe through my nose somehow to prevent this.
How can you nose breathe doing intervals?
I have no troubles in cooler air.
No smog alert but there is some fire smoke.
I asked a doc I know and he though it may be exercise induced asthma but he said there is no way I could do 4 more hill climb heats if that was the cause. And he also said smoke, humidity, heat, dust all are contributors.
He said it's something I may have to live with seeing its rarely happens.
And no, you can't nose breathe during intervals. I sure can't. I pay a lot of attention to getting my airway open and as straight as possible considering position. Tongue forward. Throat open. Belly breathe until I start panting. Also have EIA. You could try an albuterol hit and see if that made a difference.
Went for a nice 50km ride today and pushed the wind on the return leg. Tried some intervals, hills, and sprints. Got my HR up to 180 and I feel fine.
I read today that if you warm up good before a max effort this problem is minimized somewhat. And now that I think of it I felt fine after the road race as I was well warmed up.
I didn't warm up at all for the hill climb heats.
Just pulled the bike out of my truck and lined up. And in seconds my HR was 180 or so for the climb.
I wonder if there is something to this.
