Update
The challenge with making a big change in an aspect of your life that's "been that way" for 35+ years is that your body will tend to complain. A bit!
It's now 8 weeks since the Achilles went, and I've just completed a week of running without pain. I can still feel it lurking, and so I'm still taking 2-day or 3-day breaks here and there, but it's definitely better than it was 2 or 3 weeks ago.
I haven't compromised on the shoes - I'm still using the flatter/flimsier soled shoes that I've been running with for 9 months now, despite the physio advising wedges in the heels.
I've not been to the track, and I've eased off the speed.
The new style is still in place - feet landing nicely under the hips. But I'm landing flatter footed than perhaps I was 3 months ago - I'm not trying to run on my toes all the time.
I chuckle when I read back through this blog. I never knew it would be quite so hard to change running style, and the two injuries I've had (fractured metatarsal, inflamed Achilles) are classic move-to-minimalist-shoe injuries.
But the new style just feels so smooth and light. There's no way I'm going back to the old way.
I joked with a running friend the other night. I'd been running 37 years with the old style, and it served me very well. All I need to do is run for 37 years in the new style, and I'll be sorted!!
