Predict my 1500m time!!

4:02

3:57.

If you are well conditioned across middle distances, an 8-12% pace slowdown is common going from 800 to 1500, so your best case is 3’53” and worst shouldn’t exceed 4’02”. Your slowdown from 400 to 800 is 12%, which is on the low (good) side as that transition typically entails the worst pace slowdown for a doubling of distance at any distance for most runners.

What is your best 1500 time previously?

Those workouts suggest something like 3:55 to me, although if you haven't had experience running close to that it may be tough. As the a previous post said, you could be good for anywhere between low 3:50s to a little over 4:00.

The 1200 meter time trial is encouraging - it seems like you should be able to solo a 3:55 if conditions are good - cool and no wind. But will you have rounds to get through?

My advice is to focus on racing. Put yourself in the mix with the leaders if possible, although if the pace goes faster than 2:03 through 800, you might want to back off a little.

4:03 is my previous best.

I'd say your 1200 meter time trial is probably a little bit better performance than that, and it seems like you are ready for a breakthrough.

Speaking from personal experience, I dropped my PR from 4:03 to 3:59 in one race, then had a couple races of 4:01 before I ran 3:55 to end the season. A couple seasons later, I opened up with a 3:56 and then ran no faster than 3:58 the rest of the year. Then in a later season, I only raced twice and ran 3:59 followed by 3:52.

All of that is just to say that your improvement may not be linear - don't let your mind be the limiting factor in setting a big PR, and on the other side of the same coin, don't get too down on yourself if you don't have the big PR you expect in this race.
