I've been a decent distance runner throughout high school but I've suffered numerous injuries that have left me out of training for weeks at a time. During this injury time I would go to the pool and do a "pool workout", actually I had no idea how to swim or anything so I wouldn't get a real good workout in. As time passed I learned the crawl. This year is my senior year in high school and I ran xc, swimming laps in the morning (1600m) all crawl. I remained injury free and had a good season. I swam during the winter on the swim team and learned all the strokes. I enjoyed swimming quite a bit and noticed many similarities to distance running in terms of preperation, pain, ect. Anyways my real question is now that swimming is over and track is starting I'd still love to incorporate morning swims to help my overall aerobic conditioning process along. I have time for about 2400m of swimming before school. What type of swimming workouts should I do in the morning to complement my running schedule??
