New triathlete, old runner

I have always been into sports, but never really endurance ones.  During the spring of my freshman year in college while everyone else I knew was out drinking, I was the guy out in the distance running and riding around on my road bike.  That spring something just clicked.  I ended up doing my first marathon the next year.  After that I let myself get bogged down with school and working and really fell of the wagon.  THis was a big fall.  I'm practically starting over, but in these past couple of weeks I have been putting in the time again, and I have really come to see that once again I have the heart, I just need to put in the time.  So right now I am training through the winter for my first sprint tri which will be in mid-april.  My goal is not to finish, as it has been in the past.  My goal is to excell and push myself to grow and become faster.  Eventually a 70.3 and IM are out there waiting for me.
