Over the past 10 weeks of training for a half-marathon PR (personal record), there have been many times when I didn't think I could run the goal times listed in my training plan. I literally had to talk to myself and tell myself that I can run those track repeat times and that I can do the tempo times listed. Hitting those times were tough my first four weeks and many times, I didn't hit them. I kept going and have seen in my recent runs how that determination has paid off. I'm running 9-10 mile runs faster than ever. Throughout my training, I believed in the process and, more importantly, I believed in myself. Begin your training expecting great things of yourself and then go out and achieve them.
