pace

This morning I was running at 4:30am through the outdoor mall at Easton Town Center, where my gym is located. I am now putting in crazy hours to train for this Ironman Triathlon race in September. I know my biggest problem is going to be keeping the right pace. All the races I have done in the past have been a whole lot shorter than 12- 14 hours. So my constant question to myself is: "Can I keep this pace up for 13 hours?"
Actually, our lives are kind of like this. Sometimes, we run at a pace in life that can't be sustained. If it is for a season, then it's OK, but if it's forever, we will eventually burn out. The key is finding the pace that is both sustainable and effective.

So, with your life, how is your pace?
