Goals For Fitness

My goal for Physical Education (P.E) is to jog/Run as much as I can, slowly pushing myself to go further eachtime. My ultimate goal for the near future ( with in the next 2-3 years, maybe next year ) is to run "x" amount of km's for a good cause, like the Sun Run. I have never ran one and would really like to experience it. I'll know I have achieved it by doing a big run and self reflection.
