It's when the discomfort strikes that they realize a strong mind is the most powerful weapon of all.

When things are tough, you get tougher.

If we let our head drop, our heart drops with it. Keep your head up, and your body is capable of amazing feats.

There is a special mystique about the marathon, for example, because of its length-but that's just the bit you do at the end of an Ironman

If there is one thing I have learned, particularly in my life as an athlete, it is that our limits may not be where we think they are. And, even when we think we’ve finally reached them, the next time we go there exploring we often find that they’ve moved again.
