Does your bike have a granny gear (i.e. is it a triple or a double)? Also, are you using panniers or a messenger bag?
I have 3x7 gears, so, plenty of choices down in the granny gear land. I'll be using pannniers, but for today, I had some clean clothes at my regular office waiting for me.
I couldn't imagine doing ahill like that on a Fixie.
