800m time trial prediction

Training Advice/Discussion

2 months ago 05/14/2024 6:47pm EDT

Instructed to run 800m as a 'time trial' - about 1000m pace so basically all out. I was hurt in February and barely ran in march so I've just been base building to have a great XC season as there was no point in rushing me to run a crappy 1500m when we have no shot at winning conference.

My past month has been 65 mpw with 2 workouts and a long run. Pretty much every workout has been tempo / threshold intervals (ex: 6 mile tempo in 31:00, 7x mile tempo at 5:08, 12x1k at 3:11, etc) with a few 200s tacked onto the end of one per week at about 27-28 pace. What could I run? I've hit 12.7 occasionally in submaximal flying 100s.

- I ran 1:55 off 5:20 tempo pace and 13.2 submaximal flying 100 pace with no specific 800 training.

With that 100 time you should be capable of a 1:46 if you have any sort of endurance

57 should feel slow enough. I’d say 1:55

re: you have endurance right?

A flying 100 in 12.7 means he can average 13.2-13.3 seconds for a whole 800?

"submaximal"

"submaximal"

I feel like most people say "submaximal" to mean not 100% all out but very, very close

I knew someone who referred to a 3000 run in 8:30 as a 'submaximal' 3000 effort when his PR was 8:28. I think he was in 8:20 shape on that day, but it's still very tough

The 800 is a very weird event. You may be significantly fitter and run the same time or slower. You may drop a 1:50. Really hard to say. I would guess around 1:55, what you ran before.

Agree, very hard to say off these workouts. I could never, ever run the workouts OP has run. Those tempos would have destroyed me. I'd never do a 6 mile tempo, but if I was forced to it would have been at 6:10 pace. But I ran faster because I had decent wheels, consistently under 12s for a flying 100m.

I ran my best 800 off low mileage and low intensity. No idea why.

But I was able to run within 1 second of it off medium-high mileage and decent intensity (though a ton at tempo) so I was much better at 1500 and up.
