Be thankful they're allowing you to compete! They have a rule that applies to all sports and minimizes risk to everyone. While I don't enjoy wearing a mask myself and I think the possibility of transmitting the virus outside is low, I do it because it minimizes risk and makes other people more comfortable. If you and your competitors are all doing the same thing it's just an extra challenge. No one is asking you to wear an N95 - the gaiter-type masks are not hard to breathe through. Stop whining - it's not forever - just suck it up for this year.
