;However, once you start increasing mileage, chances are you'll slow down to be able to complete the extra mileage. Or at least that was my experience when I went from 35mpw to 50mpw.
PRs: Marathon (2:49xx; '13) Half (1:24:13; '15) 10k (37:25; '14) 5mi (29:23; '13) 5k (17:27; '14)
I have noticed the same thing with my easy pace as well, it's faster by about 45 seconds/mile on average.
But it is winter, when 100 comes, well....
