Half Marathon Workout-Time prediction

BUMP

Yeah, I'm biting. lol at 800s on a treadmill as a HM predictor.

I'll say...75 minutes for the half

that's based on you doing almost a yasso 800 workout in 2:35, which would suggest a true 10 x 800 yasso 800 workout in 2:37. Which would suggest a marathon in 2:37, which via mcmillan would be a half in 75.

the wildcard is the treadmill part - my numbers might make sense on a track, not sure how the treadmilling affects it.

is 75 close to your goal?

75 is my goal,5:45/46 pace. I don’t mean to ask just based on this workout alone but just throwing it out to see what folks thought. Assuming the treadmill is somewhat accurate, is this a decent indicator? About 3 weeks ago i did 6 by mile with 2 min rec at 5:30 pace on a track.

You ran 2:34 avg at 800s right? I think I could do that training at 2:22-2:26.

I think I can run a half marahon in 76:00-78:00.

when I could run 2:22-78 minutes you could run 154/142*78= 84:36

When I could run 2:26-76 minutes you would run 154/146*76=80:10

* I have bad endurance.

It's hard to predict. But my prediction would be between these 2 times I posted.

I must have more endurance because I've ran a 78min half without the sort of workouts posted above.

But I can make an other prediction too. Assuming you did the 6 by mile at 10k pace.

That would give you a 10k of 34:11-> that's a half of 1:15:30.

I would like to think I did!

Bottom line, it's hard to predict from these workouts.

Did you recently ran a race. That would give so much more information.

Did a 5k at the end of a normal milage week a few weekends ago, shade over 17min. I would consider it a time trial type effort.

If you were rested, you probably could've hit around 16:45ish.

Based on your 800's, and the fact that I personally can run about 4% faster on a treadmill as opposed to outside on a reasonably not pancake flat loop, I'd say 157s/800 * 1.04 = 163s/800, or 2:43 for the half using the Yasso 800 method. This puts you at 1:17 for the half, using McMillan, and 16:43 for the 5K. So the two work-outs seem to jive.

So I'd say 1:17, if it's a flat course, and weather is ideal.

Thanks for the feedback, any good workouts you have done to show you were in shape to run a 1:15-1:16? Considering I have about 2 months before the half.

3x3mile, 2-3 mins rest, 5:45 average
