I somehow missed that thread when it first popped up.
Thanks for reviving it as I am currently on 3 to 4 runs per week.
My goal races are short trails (5 to 15 miles for now, considering moving up to 20 miles sometimes) with a bit of vert without being full-on mountainous.
For now my typical week would be :
- one long run (approx 75 to 100 minutes) on varied terrain (mostly trails, some hills). Mostly easy effort but by feel (no strict HR restriction although I very rarely go higher than 140 I would guess - I don't have a HR monitor, just measure it the old way when you feel you've just made a significant effort).
- one shorter easy run with a handfull of strides at the end with longer jog recoveries
- one workout I tend to think about as a sub-T (typically 10-15min warm up then 3x7min30 @ approx 2hr race effort with 2min30 rest then whatever is needed as a cool down to come back home but I can modulate for some other structures keeping the idea of longer intervals with some healthy dose of recovery in between and at least 20 minutes of warm up and cool down at easy effort around that). I sometimes check my HR at the end of the last rep and am happy if it's no higher than 160, but the main thing is that it must feel like something I can sustain for 2 hours.
- if I have time for a 4th run, it would probably be a non-taxing speed/power work, which could also be interpreted as glorified strides. Typically a longer warm up then a bunch of 30s accelerations from recovery to all-out with 2min jogged recoveries. Usually on not too steep trails as I see benefits in doing them from very slight downhill to significant but still runnable uphills. If I spent more than 2 weeks without this session, I could swap the sub-T session for this.
I'm not saying this is optimal for everyone. I just like that schedule and feel like I'm progressing whithout feeling fatigued. It also alignes well with some of my beliefs in what I should train in my situation and how I can train those elements.
