Did same route last night. I think the wind was blowing the other way though, since i easily maintained an 18 MPG average on the way out. The last few miles really sucked though, pretty decent headwind pretty much blowing directly at me. Even so, i managed to cut about 8 minutes off my time. Thats an improvement! Also went soda-less yesterday and plan to do the same today. Had a slice of melon with dinner last night - ah, so refreshing!
