Hello, newbie from NY

Just started training for my first triathlon (a sprint on long island).  I have run for many years (though have not recently due to back issues).  Decided to try triathlon to get more diversified exercise (i have no muscle strength outside of the few I use for running) and for the challenge of it (I can't do more than a lap or two without being out of breath and am about the same on the bike.)

I know it is just a sprint but still a bit nervous about getting up to speed on swimming and biking (and getting back into running), but looking forward to the challenge.  This forum has been a great help already and I will probably have a lot more questions along the way (apologies in advance for the newbie questions.)

Thanks for all the advice and inspiration.

Peter
