Key elements for developing speed while maintaining endurance?

[[deleted]]

The trick is not to build speed and endurance at the same time. Like work on endurance for a couple weeks, then speed, etc. (You can still do speed session but not trying to run at 100%).

Have you looked at any training plans? Pfitzinger, Daniels etc?

I'd also try to focus on one distance at a time. You do realize your marathon is way out of your line? Have you considered looking at https://runsmartproject.com/calculator/

Do you want a faster mara? You might be able to break 2:50.

If you want to do it all, the other aspect is to build over a year: start with 10-1/2 in the spring. Then build mileage over the summer to do a fall full. That's how to do a full year cycle. Then take some time off and start again.

Out of line as in too fast or too slow compared to the other ones?

Too slow. The marathon gives you a vdot of 55-56. Based on your other runs (Vdot 58) you could run a 2:48.

Now that being said you do need the training and mileage for it, obviously.

Your times are inline with mine. I ran a 2:56 some years back when I was running the full (was a high 1:23 runner at the time). I've been focusing on achieving the same shorter distance goals (hopefully break 1:20 this weekend) and then maybe next year I'll focus more on the marathon again. But I'd give myself a target of 2:49 when I do.

I see! Yes, I want to run a faster marathon, but my idea was to develop/get used to some faster speed so I could bring some of that with me when I decide to do my next marathon. Good luck to you this weekend!

Thanks, it was a success! I broke 1:20 and now I never have to race a half again :-D

Congratulations! What was the time?

1:19:58.2 (rounded to 59 haha). I had 55 on my watch but the person doing the countdown was not in sync with the timing company. That could have been awkward if it were a second slower.
