I ran a half marathon averaging a 735 pace. And then today I ran a 15 miles, averaging 733 pace. I did the math. I took the last 2 miles off and I was like, through 13 miles, I ran like a minute 45 quicker than I ran a whole half marathon. So if I added 0.1 to it, so it's a half marathon, then I would have ran a half marathon today at a faster pace than I ran the half marathon last year in a race setting
