I just started commuting after a 2 year hiatus. I was cycling in Raleigh, NC for 3 years but now I am in Seattle...lots more hills and this, a lot more slow going. I am doing approximately 22 miles one-way from Seattle to Kent. I did my first ride this past Friday and took just over 2 hours. I expect the time to improve as I do it more and because I just switched out my 700x40 tires for some 700x28 Specialized Armadillo's...should improve my efficiency Looking to do this commute 3-4 days per week.
