Tomorrow being a day of complete rest, you'll have even more time to recover from Wednesday's hard workout before facing the weekend. While doing your strength training routine and moving from exercise to exercise, don't rush and don't waste time chitchatting with friends. Stay focused on your workout by stretching in between. You don't want to lose your flexibility, which can happen if you forget to stretch. Stretching while strength training provides a double dose of conditioning in a minimum of time.
Rest is always an important component of any training program.
On this particular Friday following your first day at the track, it will provide just that extra dose of recovery necessary for you to have a good weekend of workouts. Remember, the focus on this training program is quality more than quantity. You can't achieve quality in your workouts unless you come into the days you run hard well rested. This means getting a good night's sleep tonight too. Social considerations aside, you probably don't want to hang out all night at the bars, then be forced to get up the next morning and train hard.
