Teal has a great blog. Any of her posts would be worth cross-posting here.
But I think her latest post, in which she recaps her Army Ten-Miler experience, is a particularly good one: not just because she averaged faster than her 5k PR and set a 10k PR on the way to a new personal best for TEN miles ... but because it really exemplifies the power of persistence and positive thinking - or, as Teal puts it, No Negative Self Talk.
"Anytime I thought I couldn’t do this, couldn’t keep this pace,
couldn’t keep running, I would just bat it away. Bury that thought somewhere
else. Because most of the time when you think that, you are still doing it: still running, still keeping the pace. Often, it’s only after you tell yourself you can’t that it becomes true."
Read it, kids.
