Running 1:40 half on 30-40 mpw?

I'm in high school and can go sub 1:20 off 40 mpw easy.

I think so. Because of age/injury proneness and lifestyle, I cope with 1/2 training off 20-38 mpw typically, with one day off and 1-2 days weights and easy cycling or elliptical. Recent results off such training have been 1:34-1:39 in mid-50s. I realize more miles would be better...

Good luck! Report back, please.

I did 10 miles today, 60% effort, Columbus OH. Rainy and cool (finally). 72'F and 78% humidity.

1:27:37 (8:44) but was going at talk-test pace so I wasn't breathing hard. I'm used to running in 85-93'F weather (9:12-9:40 pace) so this is like heaven.

Last year I ran the 1:45 half in crappy heat too--75'F and 80% humidity, plus 25-mph winds in Columbus. Everyone's times were bad. I had no comparison as I had never run a half before.

Today's effort gives me hope I can run 1:40 in cool weather, and with more speedwork. The 10-miler I did today had various hills throughout too.

Im a skinny 26 year old male. I have been running about 3 years pretty casually. I just looked back at my strava data. Last year i ran 1:42 off of 15 mpw + 2 bike rides a week. I wouldnt consider myself talented.

This year i went 1:32 on a windy day on a hilly course. In the 4 months before my half i had only 2 weeks were i hit 40 mpw, but i also took 3 weeks off for an achillies injury. I averaged a little over 25 mpw going into the half. I took workouts a lot more seriously though.

If thats anything to go on, 40 mpw consistanty with some decent workouts should be plenty go go under 1:40

Durianrider ran a sub 3 hour marathon on half that mileage.

Yes, if you are consistent, running the mileage each week, and stay injury free. I've done low to mid 1:30's in my 50s off that mileage. If you're younger, it might be much easier (see the post by the high school student above - I'm not shocked based on my own kids). Personally, I find the 12-14 mile long run prepares me better for the race, but if you're running only 30 miles per week you need to watch out for injuries.

Wow. Sub 3 hr. 'thon on 15-20 mpw? Natural talent?

Did the 10 yesterday but was also told to go at least 14 for half training.

I ran 1:12 on 30 MPW. The question can't be answered because we don't know what your ability is. Your real question should pertain to achieving a % of your maximum. I would say that you can achieve 80% of your max 1/2M on 15 MPW. You can achieve 90% of your max on 25MPW, 95% on 40 MPW, 97% on 50MPW, and 99% on 60MPW.

What are your shorter distance PRs? What is your normal training pace? How old are you? What was your half time last year?

Yes, it CAN be done, but we don't know enough about your running ability to construct an answer and a potential training plan for you.

FWIW, I'm a 30 yo male who runs 25-30 mpw and i'm a consistent 1:20-1:23 performer.

I ran a 2:59 marathon on 25mpw, maybe 12% body fat. No HS or college running experience, about 2.5 after I started running regularly. Do real workouts. Eat and supplement right. All I have to say.

2.5 years that is.

I am a 34 y/o male. 5'2". 150 lbs.

Running on and off since 1998.

Mile-5:15

2 Mile-11:30

5k-18:33

10k-44:30

10 miles-1:14 ish?

13.1-1:45:46 Columbus half, 10-15-17

Training pace: 8:46 easy/normal, 7:55 hard. Marathon and longer pace, around 9:20 projected.

I've got busy lifestyle too. 30-40 mpw is plenty for that time. No speed-work required, just run tempos. Increase your long run to 15 at least.
