if trying to get a sub-2.48 mark in June at Grandma's, what seems a reasonable late fall 1/2 marathon goal?

well, the merv calculator says 13.11 miles in 1:20:01.3 (6:06.2 pace) equals a 2:48:00 marathon, if you believe in such things...
Run it fast enough so that you can finish up in 2:48. Say for example, you run 1:30 for the first half, you'll need to run sub 1:18 for the second half. Perhaps, the best approach would be to run 1:23-24 and then hold on or run faster. Just remember, that you want to run under 2:48, so don't run 1:48 for the first half.And calculators are good for math not for running.The Big Dog.

That 1.20/2.48 ratio is do-able. But if your distance/aerobic work has not been so good or consistent, you won't make it. Which would mean you would need a faster half (sub 1.19) since you will "die" more at the marathon distance.
So it really comes down to your training. (1.20 Half + 4 mins) x 2 is definitely possible. But some with that half time have run 2.50.
Check yr diary, are you well prepared?
When I ran my 2:48, I came through the 1/2 M in 1:17. I came through 20 miles in 1:57, and the I ran 49 minutes for the last 10k. That will give you 2:48. I highly recommend NOT doing it that way. The death march from mile 23 to the finish is not fun. I suggest going out in 1:20-1:22 the 1st half.
...if you're a "true marathoner" with some experience, the Purdy table conversions (which essentially work out to multiplying a shorter distance time by 2.1 to get a longer-distance time when the longer's twice the shorter and the shorter is at least 5K) may actually apply, but for most, they don't. Experientially, you probably need to be in sub-1:18 shape to be able to hit 2:48.
What are your 5K and 10K PR's?
Only because I recently ran 2:43 with a 1:18 half marathon PR which I ran while in training. I'd say he's being a bit conservative. ...having said that I was obviously in better shape on marathon day 3 months after my half marathon
1:19 I think would put most people in the 2:48 range provided of course you have put the mileage in in training.
I found that the calculator in Mervs pretty much hit all my time projections bang on the nose or very close to it. I ran a 34:43 10K a month before running 2:42:55 in the marathon...the calculator projected 2:42:02 (there was a killer hill in the last mile)
Some people are freaks though. Chris Clark's best 1/2 is 1:15:mid to high, and she ran 2:31:something on a hot day at the Olympics. She can arguably run faster in a 1/2, but her 5K PR is pretty slow too, just a bit under 17 I think. She seems to be semi-retired and running only 60 mpw. However, earlier this summer she ran a 1:16:mid to high half marathon and last week she won the marathon here in Anchorage (2nd overall) in 2:38:something on a rolling course with extensive "tank trail" fire road sections.
...was on such a rapid improvement curve during her build-up toward the 2000 Trials that she was in much, much better shape by the time the Columbia race rolled around (and certainly by the time the Games themselves arrived) than she was for that half. But I agree that she's probably a "pure marathoner" in the extreme regardless.
This brings up a good point - this seems to occur more in women than men, most likely, I would guess, owing to lower testosterone levels (and hence less raw "power") but great potential depths of endurance. Hell, look at Ndereba or even Radcliffe - how many men have run 2:18 off 30:30 or 31:00 for 10K? Not many.
Did you go 2:48?
An easy calculation is to double your marathon time and add 10 min. That would be 1:19:00 which is right IMO - good luck
17 year old post lol ?
When I`m the coach the formula is half marathon time x 2 + 5 min = marathon time .

If you are an aerobic monster like Walmsley, 1:24 should be about right.
The 1:19 runners tend to start hitting 2:46 in the marathon these days.
I could run that fast 17 years ago. Now my 400s are slower than that pace!!
