Philadelphia International Airport

I rode down to the airport for a nice lunch time ride. After yesterday's hard sprint workout, I wasn't sure what my legs would be up for. I was initially thinking to ride two hours medium tempo; a couple laps of the airport plus a lap in the Heinz Wildlife Refuge. Once I got down the airport though my legs were feeling good and medium tempo turned into a solid 20 minutes at hard tempo, just under threshold. 10 minutes recovery took me perfectly back to the beginning of the loop so I figured 3 x 20's were in order. The second 20 was very hard right at threshold while the third 20 was difficult, and not quite as hard power wise. Now that I'm home and have had a great post ride recovery smoothie, my legs are really unhappy I made them do that. Unfortunately, I might not get out at all tomorrow, so this was too good an opportunity to miss.
