W4 R2 done this morning, I found out my old heart rate monitor (chest band type) and replaced the battery, better and more accurate than the treadmill, treadmill reads 400 cals for W4 R1 where as the HRM shows 670 cals for W4 R2 plus the heart rate monitoring was continuous and not just when I put my hands on the sensors.

I can't believe, after last week when I was considering redoing W3 I'm now over half way through W4 and chasing down W5 and the first long 20 minute run (gulp).

Thanks all for the support so far, the fact I'm now officially a jogger is, in a large part, down to you all!
