The interval sessions during the week has helped a great deal for increasing my pace, but I may have overdone it. I started doing my usual 18 mile session and my legs were screaming from the first mile! Once I get dressed and ready to go, theirs no quitting though. I did the ride and felt drained, my legs didn't feel very strong at all. The positive aspect is, I managed a 18.2 mile/18.5mph/840 ft on a weak sore day. A few months back, i'd probably only manage 15/16 mph the way I felt today. I know I'm no fan of boring soft pedal recovery days, so i'll just take a few days off the bike instead.
