Well to expand on what I was saying...
I had monster headwinds both Sat and Sun. Around here it's rather normal being all flattish and farmlandy. My 11.8mi ride yesterday took me 37 minutes to ride out 5.9mi, and only 20 to ride back. When I say I was almost shut down, I had the chain on 36/13 and at times I was almost at a standstill and my legs were on fire... Funny thing is, I topped out at 24.8mph on the way back, and I'm at 15mph rider.
