A slow, sluggish run this morning with my Fleet Feet training group.  We did 8 miles, and it was cold outside, but I fell way behind.

At the end, I was looking at my running shoes (Brooks Ghost) and realized my tread on the outer right side of both shoes had worn down considerably. I got the last pair back in Sept - surprised they had worn down so much but I have been piling on the miles.

I bought a new pair (same model), and trying them on I could tell the immediate difference.  Looking forward to the next run (and the extra hour of morning sun we'll get with daylight savings Fall Back).

Here's an interesting article on what it will take for a human to break the 2-hour marathon record (Spoiler - it's not EPO).
