That is correct. I started running again 6 years ago on January 1, 2002. I began running in 1977, but left running and training regularly in 1992 when my first son was born. (This has absolutely nothing to so with the original post, or anything else about this thread.) I was a discus thrower and shot putter in HS, coached all aspects of T&F - not just running - and refused to just go running with the team the way the guy I replaced - my head coach in HS - had done. I coached for my paycheck, he ran.
You're not trying to be a jerk and are trying to be helpful.
My last 15k race was around 76:00. Not fast, but not a disaster of pacing either. Hit the first 5k mark in 24:00. Hit the second (which was almost all trails) in about 50:00 (26:00 over the 5k). Ran the last 5k in about 26:00. I should have been able to return to a sub 8:00 pace over the last 5k, as it was back on the road, but couldn't/didn't. So yes I went out faster than my average pace for that race, but no faster than I should have - the McMillan calculator suggests that I should run a 15k around 68:00 if trained properly for the distance, based upon a 5k PR of 21:18 6 months earlier. I felt that I'd trained properly for the 15k, as I was in the tail end of HM training. A 68:00 5k is mid 7's. I ran mid 8's, starting just under 8.
I still think that it's interesting that there is such a drop off in my times over the 10k to 15k distance. I think it's probably mental, or that I've just had a couple of bad races. And in response to the OP's question, I'll say that for me, it was fairly easy to run the 8-9 mile pace after just a few years of regular, committed training, but very difficult to carry that out to the half-marathon distance. After two attempts at the half, I' around 10:00 pace for that distance.
