1st timer from Texas

Hello all. Came across this site looking for advice on a training plan. I'm a recent divorcee and was kind of in a funk and needed a challenge. I was talking to a friend of mine in Florida a few months back and she said I should do a triathlon. Challenge accepted. I'll be doing the Olympic distance tri at the St Anthony's in April. I can't be more excited. Being 46 years old and out of shape, my body really curses me before, during and after every workout. I've been at it for a few months now, working out 5-6 days per week and REALLY enjoying the rest days. I didn't realize how much goes in to something like this. Fortunately, my friend used to do the Ironmans and she has been extremely helpful. I guess I dont really have any questions at the moment, but I'm thanking you all in advance for all the questions/advice that I will have.
