Red nose reaction during training


New to the forum, not the product. I am the winter training guy who falls off when it gets warm and my A race is done. Here’s my issue: When I start doing my structured training on the trainer each year the bridge of my nose gets red. It usually goes away within a day but comes and goes pretty consistently. Anybody have this issue? Is it a breathing issue or am I breaking blood vessels in my nose?

Thanks in advance!!
