I started with the short run, as I'm tired from my core outwards, despite a good night's sleep. As I hoped, it's actually shifted some of my sluggish feeling, but I didn't want to push further tonight. Pace a bit slower this evening. Feel energised now though.
It's a bit further than 2.5k because my old lady eyesight isn't brilliant for reading my Garmin in the dark, even with the backlight on, so I only look from time to time. Don't want to set it to buzz me every half km as that would drive me mad.
I didn't try the intervals as I was tired setting off, but because I'm running up and down inclines all the time, I reckon I'm doing them inadvertently anyway.
It's really good to have a plan to work to. Thank you ju-ju-
