Training for my first tri
I am training for my first tri which I need see if I can still get into. I decided to do this tri a couple days ago, which is on September 19th. The swim is 800 meters, 18 mile bike, and 5k run. I have the bike part down, and I getting out and running. I did a 1.3 mile "run" (it was a jog) this evening without stopping. That is a major accomplishment for me because I have not ran that much in the past 10 years. I felt like I could do more though so thats encouraging to me.
Now for the part that I am concerned about, swimming. I am not a strong swimmer, I really dont care to swim honestly. Is there anything I should do to get comfortable in the water? The option that I really have to train for the swimming portion is in the river. The local pool is filled with kids till closing and the Lap swimming time is while I am working.
