[IPk] Running and bg's
First and foremost thanks for such a thorough reply - you have given
me lots of food for thought already.
I have answered your questions in the text.
Have a good weekend.

[Audrey Sheal] I must confess that it is my choice not their's!
What I find is that if my bg
is above 11m/mol I have to give myself a small bolus before I
exercise or I go shooting up high.
I exercise first thing for a few reasons - it means I do it!! I
have time!! and then I go home shower,
eat and get to work. I also find exercising on an empty stomach
easier - for some reason, probably
psychological! I find that starting on a bg >6m/mol is ok and less
I would drink some fruit juice first.

[Audrey Sheal] I used to do 30 of other CV, and now I am doing 20
of other CV and then
10 of running after that. That in between would be a good testing
