emzap, I'm thinking about all sorts of other exercises at the moment - aqua jogging wasn't one of them right enough - I just don't like water that much!!
I wonder if a treadmill would be easier on the heel? I have bought one for my wife for xmas (and made sure it is fast enough for me because I suspect that, even though she has begged me to buy her one, she will use it twice and then it will sit idle).
Anyway, today's approach to PF is the 'no pain, no gain' approach - so I blasted round 6 miles in 43:20.
Another 4 miles this morning taking my total for the year to 1975. I have only done 30 miles in December and don't think I will make 2000. Heel was sore during the run today so I am clearly not cured in any way.
