Hey man, I am still following. Though in less frequent visits. Not a lot of training talk happening on the boards these days, which is a bummer.
Your situation is tough, but we're all kind of in a similar boat (my spring marathon was canceled, and I'm not totally sure where I'm going next). And in my opinion, you almost can't choose wrong. And my advice would be to pick a short term and a longer term plan that your gut tells you will be the best. That means the most exciting, interesting, and easiest to keep doing.
So if you want to sharpen things up for a few weeks and do a few time trials, go for it. Then take some downtime and shift over to summer cross prep and building those base miles.
If you're liking what you've been doing and want to get up to 80 mpw sooner, then you can do that, too. It sounds like you might be a tad mentally fried and maybe physically beat up. So you could take anywhere from 3 to 10+ days of slightly reduced mileage and nothing but easy runs. Then start building back up. No reason not to do 80s in April if that's what you want to do.
I think our sport makes it easy to think in seasons and big races and specific buildups. It kind of forces us to be seeking more all the time. Faster splits. Or more miles. Or anything that shows us the hard numbers that we are, in fact, progressing and getting faster. And that's a hard space to live in for the long term.
One of the things I love about following this thread is that you're doing the kind of training I wish I did at your age (I think I said it sometime before, but I'm almost 40 and went to HS in the 90's when all we did were intervals that were too hard and too fast). And from what I can gather, you've got a really good thing going. So I think you should keep following that.
And I don't mean keep following the same plan you've been doing for months (though you certainly could and would be fine). I mean keep going with doing the training that you're enjoying and responding to. Keep developing your own, personal theory of training and what works best for you. Because the other thing that is so easy to lose site of in the running world and on these forums, is the next best training method. Just when you think you've got a good thing, you learn about some other element that you haven't been doing. And you think, should I add that in? Maybe. But you can't add everything all the time. And again, that becomes another form of chasing.
So train the way you want to train. And also know that (how old are you, 17?) your high school running is not all there is. You can continue to improve for decades. I train with runners from their early 20's up to their early 50's. We all take it seriously. Some of us are not as fast as we used to be. But quite a few of us are putting out times that crush what we did in our younger years. It's all about finding enjoyment in consistent training. Whatever that is for you.
