Some good advice already. But I think your goal is unrealistic. Like the others have said, make your goal completing the event and don't worry about being in the top 10. The trouble with most training regimens, including the P90X is that they are designed for people in their 20's, who still have bodies that can recover in 24 hours from an intensive work out. The same routine, as you discovered, doesn't work for a person in their late 40's. You end up getting injured, discouraged and then give up.

Start with an easy training schedule, then build up as you gain stamina and lose weight. The idea is to be pleasant tired after your work out and able to hit it again the next day. I've assisted a number of friends that wanted to get back to exercising. I would suggest something along the lines of the first week try and do 10 push ups, 10 sit ups and a 20 minute run walk. Second week up that to 15 push ups, 15 sit ups and try to jog the entire 20 minutes. Third week alternate each day between a run and bicycle, including the push ups and sit ups. Then add swimming. In 90 days you will be able to complete the event.

I know the 10/10 pushups/sit ups seems simple for the first week, but the idea is to wake up your body to the idea that your are getting back to exercising. You will also be surprised to find they are harder than you thought.

Finally, see if you can find someone that is willing to do it with you. That makes it easier to get out and do it every day.

Give it a try. Oh, and I turn 58 next month.
