Half marathon prediction

Bump

1:13 to 1:14 is aggressive based on what you've posted. I would guess 1:17 or so.

In my opinion, I think that things might change in terms of fitness within 6 weeks. I probably will run a 1:17 if I run a half marathon right now.

I havent started interval work and I will next week.

interval work next week? you're one of those old school folks that doesn't funnel towards race specificity, huh?

I’m almost 26 and I just follow what my coach plans out for me. I also have a 5k end of season.

All he told me was not to expect too much because it’s my first half ever.

Strong workouts. Looks similar to what I've been doing and I went 1:16 for my most recent half. The half is no joke but right now I would say 1:15-1:17 sounds reasonable. I feel like for 1:13-14 you need more pace work in the 5:30s versus the 5:40s.

So I'm preparing for my first half marathon as well. My workouts are very similar (6mi tempo@, 6xMile)...

my question: Is it normal to be doing 6 miles of workout and then be expected to maintain that pace for 13 miles??

As a 5K/8K guy, I feel miles 8-13 are going to be ROUGH. Some workouts coming up include 12 miles at long run pace then 4 at half marathon pace but when prepping for 8K we would always get a workout that comes out to at least more than half the distance...

Could things possibly change in the next 6 weeks?

Idk, but I do remember Mo and Galen ran a half on 10k training.

Also, for half and full marathon, it’s impossible to do workouts like 13x mile or 26x mile.

When a real ace coach he doesn`t say things like "don`t expect to much" . A real ace coach tells you exactly in race time prediction what to expect! :)

FYI my 5k Pr is 16:02

Recent workouts:

- 6 x 1K, 2 min rec: 3:25, 3:19, 3:19, 3:16, 3:11, 3:11

-6 mile tempo: 34:43 (5:54, 5:53, 5:52, 5:49, 5:42, 5:33)

-10K race: 35:34 (9/9)

- 2 x 3 mile 3 min rec in between: 17:32 (5:53, 5:52, 5:48), 17:09 (5:49, 5:49, 5:31). This was during a 80 mile week

-4 x 1 mile 2 min rec: 5:19, 5:18, 5:19, 5:12. This was during a 80 mile week.

- 3 x 2 mile 2 min rec in between: 11:18 (5:38, 5:40), 11:25 (5:48, 5:37), 11:14 (5:37, 5:37)

-Long runs are 15-17 miles.

-Racing this Saturday in the 8k.

Is 1:14 possible?

If your 5k is 16:02 and you say in your next post your recent 10k is 35:34 then bad news for you is that you are slowing as the races get longer. A 16:02 runner should be hitting around 33:30 if well trained for the distance. Maybe your coach told you not to expect too much Ashe knows you aren't ready and slow as the distances increase. Your 10k time indicates 1:17:30-1:18:00, that's if you don't slow further.

I see you running like 1:16:30 at best, but probably around 1:17 like others are saying, unless you are really taking it easy in your workouts, and like the post above says, your 10K time is significantly slower than it should be for someone with a 16:02 5K PB.

Were you going all out for the 10k? If you ran all 13.1 at the pace of this 10k you’d be over 1:15.

The 16:02 was on track. The 35:xx was on road. My Pr is 34:1X at a XC course. When I ran the 10k, the splits were close to consistent, but I can feel the lack of speed. During that week, I did 2 hard workouts as the race was on a Sunday (6 mile tempo and also 5x1200s). So in some way, I ran on tired legs. Note that I’m running other races after the half.

I train by myself.

Half Marathon: 1:16:XX
