As long as you're far enough into your training for the half...which I believe would only be a couple of weeks from now? You will have plenty of time to continue for the full. It's your first, so take it easy and have fun!
So that's me, and that's my story, and I think you guys are all awesome, and I'm really pumped to be training for my first marathon, and I wish you all the best of luck because RUNNERS RULE!!!!
The only wrench in the plan is that I've gotten so fast training for my marathon that coach found out and wants me to run the two-mile in track, and so now I'm torn between training for 26.2 miles and training for 2, which are two plans that don't really mix all that well.
Tougher than most, dumber than the rest. "You can not count the miles until you feel them" TVZ
