Another Newbie...

if u can stay afloat during the swim, u can do the tri....try the plan at http://www.beginnertriathlete.com/Programs/16wksprint2x.htm  it is the easiest...can u do the times comfortable in week one?  if so, start their...yeah, u will be one month short BUT if your pace is decent and you dont mind walking some in the run (walking is recomended) THEN DO IT!!!!

OR start off in month 2....that is ONLY if your fine with the volume...if your not horribly out of shape, that could be a doable option.  just listen to your body, dont overdo it and have fun.

good luck!

Sugarsnap --- you can do it.Just be consistent with your training, and don't overdo anything to get injured.

And welcome to the site.

Hi Rosemarie,

The variety of exercise in running/biking/swimming seems just about ideal for burning a lot of calories in a week and creating the all-purpose body for yourself. 

As for three months to get ready for a sprint, the answer is a resounding yes.  You can completely transform your body in three months.  Start where you are and build slowly and consistently.  An hour a day is perfect.  Keep the intensity of each session pretty low at first while you find out how quickly you can recover from one day to the next, but maintain the duration if you can.   A common problem is starting out with too much intensity per day.  Beginners tend to start with a routine that they can do for one day but then cannot sustain it for six days straight.   The increasing fatigue seems like a fitness regression instead of progress.  That of course leads to frustration, doubts about their physical ability, and even injuries from trying to push too hard.  Slow and steady progress is the key.  Post on how your are feeling to get some feedback from people who are or have been right there.  Rest is a key to progress.
