Training Halted Again

Training halted again, calf pain this time. On the 18th length of the pool last Friday I suddenly had pain in a knot inside my left calf muscle. I haven't risked any runs since but I did go for a 7 mile hill walk on Sunday which caused it to hurt sometimes. In M&S last night, I was having no trouble then just out of the blue it hurt again when I moved after I'd been hanging about waiting for Lynne.
It doesn't hurt most of the time but poking around in the calf locates a painful firm area. I think it's improving but I've been up a ladder pruning trees this morning which pulled a bit occasionally and was hardly resting it.

Getting worried as the weeks keep disappearing and I'm not even at 5 km yet. Most recent progress was to 3 x 4min runs split with 3 min walk on treadmill.   (1.7 km actual run in 2.57 km overall)
On the positive side, achilles feel fine after all this time.

Received my first sponsorship this week which is great. Feel free to join in below.
