Awesome! I just started swimming again this past May when I decided to do tri's before that I hadn't really swam any distance since HS which was over 20 years ago. I was really surprised first time back in the pool how hard it was - I thought my endurance was great from running and biking but one lap was a challenge. I was able to build my swimming endurance fairly quickly but am very slow mostly because I am not swimming efficiently. I had a first session with a coach this week which was great as I knew that I was working harder than I should be and really needed someone to tell me how to fix it. He said I was working twice as hard as I should be, so if I can correct the issues I should be able to go twice and far and hopefully faster.
