I was having a conversation today with a woman at work who is a big triathlete! She's done tons and really trains year round. I told her that I am training for a Sprint. Other than my husband, she is the first person "in real life" that I have told. She advised that after EVERY bike run I should go for a short run (1/2 mile to 1 mile). She said that there should be "real" brick days, but that always taking a short run after a ride would really help my legs quickly get used to things. So, tonight I rode for about 30 minutes. When I got off I ran a mile. I have never felt anything like that in my life. I have done a lot of running. Once a week I run 8 - 10 miles on a long run and most days I run 3 - 5....so I know running. This run after the bike ride honestly felt like my legs were not my own. I felt like I was picking up weights. I really understand the term "brick" now (and I know this wasn't a real brick). The funny thing was, I felt like I was running like a snail. I would have guessed I was running a 12 minute mile. I literally had NO SENSE of timing. When I finished it, I had run the mile in 8:50....which is really good for me. Very, very, cool.
