. . . are harder than indoor bricks, not that this is a big surprise. Several weeks ago I went from riding the trainer to an outdoor run, and it wasn't too bad. Yesterday I rode 16.3 miles outside, then ran about 1.3 miles. My legs hurt, but not in the way I imagined they would. I didn't have jelly legs, but I could feel all the stabilizer muscles in my lower legs working and they felt sore. I'm not sure if this is because of the bike to run transition, or if it was because I had to run on asphalt and I usually run on dirt. After a few minutes it felt better, but I definitely need to keep practicing this. I don't have tri shorts yet, so I did a full change of clothes in between, I was in and out of the house in 2.5 minutes. Tying up running shoes when you're in a hurry coming off the bike is suprisingly difficult. A happy chocolate lab licking your face while attempting to tie shoes doesn't make it easier. From now on, no dogs are allowed in the transition area!
