I have started exercising since the Paris marathon.  I haven't been on any runs yet.  I went for half hour bike rides in the gym on Sunday and Tuesday.  It has been good to get back into it, although I won't really know how my legs are until I go for a run.  I plan to go for a half hour run after work tomorrow.  As we are heading into the summer and will have more daylight hours, I think I will go on more runs on weeknights.
