Return to running?

It's nearly 4 weeks since I was advised to stop running for a few days.

"...until it doesn't hurt when hopping."

Well that was this morning and so I decided to risk doing a jog/walk to circuits. It felt stiff on the journey and weak during the exercises but didn't cause a problem. I set off to walk home, when I was a bit aware of the tendon, but ended up being driven home for most of the journey.
