When I started significant cycling my throat would be a little sore the next day from breathing hard. Now it's not a problem - I can move an awful lot of air :)
Airborne contaminants can cause it for me though - smoke, dust, etc. I don't suffer allergies, but it only takes a tiny amount to cause a problem for lots of people, as mentioned below. 'Tis the season.
