I'm riding in my first century this weekend (Back Roads in VA), after a summer of training. I fit in a 70 mile ride a week and a half ago but I know I'm a bit undertrained. Work's been crazy recently too, so I've barely ridden since that 70 miler. I was feeling nervous but reasonably confident, but then last weekend I came down with a productive cough -- I don't know if its allergies or a cold or what, but I bailed on a planned 60 mile ride only 5 miles in. I'm feeling a little better today but I'm still coughing up crap.

Can someone please reassure me that I can still finish the century? Any tips on clearing a productive cough fast? I'm attempting this unless I'm on my deathbed, pretty much. It's been a tough year and I need an accomplishment like this. I could use some encouragement though!
