1500m prediction thread!

The first workout I would say 4:25

The second workout I would say 4:10-4:15.

So I will go with about 4:18 to average it out

Classic thread, hopefully I can get some genuine help.

These are two workouts that I have done at 2400m, on a proper track with a decent headwind going straight down the back straight. They were done a week apart with a couple of lighter sessions inbetween, but with only 5 steady miles the day before.

1. 10x400 off 2 min recoveries, in 75, 75, 74, 75, 74, 72, 70, 67, 64, 60. The first 5 felt pretty comfortable, and the last rep was totally balls out.

2. 1k in 3:10, 5x400 in 69, 1k in 3:10, 5x400 in 68, 800 in 2:32, 400 in 64.

4:30 breaks after each segment, 400s done off a minute, then 2:30 break after the 800. Legs were tired after the end, but felt I had at least a 61 in the tank for that final 4, but was windbreaking for someone.

Thanks in advance,

You have 4:20 ability

PRs?

at first i thought you guys were idiots saying 4:20, then i realized he asked about 1500m.

here are my thoughts: those workouts were too easy to really tell. i'd wager 4:23 if you have some 800 speed.

if your gonna do 10x400, don't do the first 5 so easy. 75s are useless for. and most 4:40 milers could rip a 60 at the end of a easy workout like that, so that means nothing to me.

for workout #2 you took too much rest after the 1000s, which makes me think that the 1000s were tough for you. so that moves you from 4:20 to 4:25 IMHO. but you managed decent paces for the next 400 sets, so i'll give you 4:23.

and windbreaking isnt worth 3 seconds.

good luck, please update later

waste of time as a predictor

Based on first workout I think you can run 72/lap =4:30 Based on second workout I think you can manage 69/lap =4:19

I predict very conservatively.

Sorry for not replying earlier.

Are these taking into account that I was at 8000ft? Just that I was definitely working pretty hard, and I am much fitter now than I was last year...where I ran 4:12, while being hungover. The final workout there was 5x1k off 4:30 recoveries, in 3:20, 3:15, 3:10, 3:05 (that hurt) and the final one was 2:58 (which REALLY hurt, flopped after the rep).

I appreciate the replies, but I don't think I'm gonna be getting slower after a month at altitude!

I don't think these workouts can be really used to predict a 1500m time. They are just not predictor workouts and the conditions you ran them in are nowhere near the conditions of a race. Altitude also has a different effect on different people so that is a very sketchy variable. If you say that you are in better shape now than a year ago when you ran 4:12, than you know you can go faster than 4:12. If you want to know what you could possibly do in a 1500m, do a predictor workout or just do a race.
