I felt sore arriving at work, the first time that's happened in years. Maybe it is just a holdover from being slightly dehydrated from the ride on Sunday - I didn't feel it riding but ran low on energy after only about 30 miles, and drank three bottles of water at home which is a sure sign. I also adjusted my saddle, which I don't adapt to quickly. Whatever it is I hope I'm over it for the ride home.
