Need help running slowly
My challenges are a little unique. I (35M) have been running on and off for two months with the medium term aim of doing a 20 minute 5km. After my first month I was able to do 3km in under 12. I was an advanced runner in high school (practically gave it up since then due to injury), I've recently built a high aerobic base from regular cycling and I've been conditioning to fix some muscular issues through a range of resistance sessions.
So obviously I've got some baggage. But my problem is that I can't do the thing that everyone says one should do to ease into running - running slowly. As soon as I go slower than 4:20 pace (yes I've tried far slower too), my body feels completely off. My leg muscles start doing more work in certain ways, even my heart rate spikes. I've improved my technique, I've been working on my hip flexors, adductors and calves, and so far I've been able to rid myself of shin splints and feel more relaxed at 4min/km, but that's about it. All the muscles just south of my hips feel off and it makes me lose it pretty quickly.
I've seen a few physios but they all say that my muscles are doing alright (though they're not running specialists). I've been trying to push through the issues, but the only effective workouts I've been able to do have been effectively threshold runs between 3:55 and 4:10, pushing my distance ever so slightly each time. I still cycle often to cross train. My progress is a little encouraging but I'm enjoying it far less than I'd like and I don't want to injure myself.
tl;dr: my starring fitness is high but my body isn't letting me run slowly so the only gains I can make are doing threshold runs
Has anyone had similar issues? Any insights you care to share?
