If you felt that the 5K was a pretty accurate race (certified and flat),
then I would have taken that time to see what my expected 15K time should
be. There are several online calculators that will do this for you. My
favorite is at http://www.mcmillanrunning.com (click on the racing link).
If you've been training with emphasis on lactate threshold running (tempo
runs, cruise intervals), then you should be able to pace yourself fairly
closely to what that site tells you. For example, if you ran the 5k in
20:00, the you should be able to run a 15k in 1:04:23 or a 6:54 per mile
pace.
I've found in the past that those predictions based on short race times are
optimistic in my case for longer races, probably because I hadn't been
running enough miles to get endurance to the point where the factors that
those predictions assume are the limiting factors. (extra credit: diagram
that last sentence) This time, however, the tables look right on. The one
at http://www.mcmillanrunning.com was really close (5K@21:37 -> 15K@1:09:35,
vs. my 1:11:02). The table in the Daniels book is the same. This suggests
that I could have hit it just a little harder, and I believe it based on how
I feel now, several hours later.

Quoted message said:15k race pace is right around your lactate threshold pace. LT pace is
around 80-90% of your max heart rate or 76-88% of your heart rate
reserve. Assuming your MHR is indeed 192 BPM (that's a big assumption),
your LT pace is around 154 - 173 BPM. Your heart rate reserve would make
it more accurate, but I dont know your resting pulse.
52 rest, 192 max -> 158-172. I do threshold runs at about 170 (+5 to 10 if
it's hot) but felt that I would have blown up if I'd hit this level of
effort too early. Maybe I was a little too conservative. I was rested, it
was cool, and I know that HR isn't the best indicator during a race. I have
painful memories of going out too fast, and my pace was so much faster than
it's been in previous races that I wimped out a bit.
Quoted message said:Were you not tracking your pace based on the mile markers? If you're not
used to racing and there's nobody to pace off of, it is difficult to know
if you're going the correct speed.
Yes, 7:45, 7:31, 7:54 , 7:41, 7:42, 7:42, 7:28, 7:37, and 9:43 for the last
1.32. Now that I look at it again the time for the last 1.32 puts the pace
at 7:36, just under my average pace of 7:38. Bad calculations in last post,
sorry. So a sudden push for the last bit was just enough to overcome
fatigue that was just starting to set in. Probably coulda pushed harder
though.
Quoted message said:It would be helpful to do enough
traing runs at LT pace to get an idea of what that confort level feels
like.
Lately I've been doing 1 mile easy, 4 hard (approx 170 BPM, + 5 or 10 BPM if
it's hot), 1 easy on some fast days. Other fast days are more like
intervals. I'll also usually throw in a mile or so hard followed by one
easy at the end of long (10-15 mile) runs.
Maybe I'll try some long, fast "test to destruction" runs to see just how
long I can do my assumed LT pace. Sometimes my schedule is such that I know
I won't be able to run for the better part of a week, so I guess it makes
sense to do a hard run just before the break in place of a tuning race.
I've hit the wall a few times on long, solo trail runs, and it's very
satisfying is a sick kind of way. After a week or so of recovery,
everything else seems easy for a while. It's not demoralizing at all the
way blowing up at a marathon is.
