Scott McMillan : Endurance Junky

Back to bike commuting, legs feel good, hard to breathe though. I think I may have allergies, I have never had allergies before but my eyes are very dry and irritated and I am also congested.
Tried do a Tempo, my coach had me down for a 16k/13k @ tempo pace. I was only able to muster a 12k/ 10k close to tempo pace (felt hard though because of my clogged sinuses).
Hope I get better soon.
