Triathlon next??

Since I've completed the marathon I keep thinking....what's next? Perhaps a triathlon?? I've been trying to get the hubby on board and for some unknown reason, he hasn't jumped at the opportunity! Figured we could start out easy with a little 1/2 marathon in February and then a mini triathlon in May....sounds reasonable! So I decided that even though we haven't signed for anything yet, I should continue to train in some capacity. I hit the treadmill and figured I'd whip about a few miles no problem! I mean, I just finished a damn marathon, anything after that should be cakewalk right? Yeah well, my body doesn't exactly agree! In fact, I'm pretty sure it was yelling loud and clear....."what the heck do you want from me??", "you need a reality check lady! You are not a 20 something super elite athlete!!" It appears that my mind and my body have very different opinions! This may be more difficult than I originally thought ;)
