I do most of my running out in the country lanes of south Wales, and i've been going up and down the odd hill just fine. When it gets a bit steep i do just what you guys have been saying - slow pace, keep the arms going, make sure i'm not running up on my toes etc.
The difference recently came when specifically seeking out a big hill challenge.
Example:
I don't know how much of a challenge it is to anyone else, but something like 250m elevation gain over 2.7k run was Wednesday evening's task.
I had planned to incorporate this into a larger run. I set off fine, the hill was fine, but i couldn't run back down. The running ended there.
That's happened a few times now. I've done more elevation change across larger distances for months, but compressing it seems to strain something.
If it was the achilles itself, shouldn't i be able to tell? Stretching it doesn't hurt, poking prodding or pinching doesn't hurt.....
