broke a barrier

did the 5k in 21:56 this morning. very proud, but it took a lot out of me. my stomach was hurting something awful when i stopped. it's an average of less than 13.5 pace, so maybe instead of starting at 13 and needing to amp up to 14 and then 14.5, maybe i should just run the whole thing at a steady 13.5...that's a 7:15 average mile, btw. i'm beginning to think i could do a single mile under 6:30 after all.
