I decided to slim down for the summer. It was expensive on the wardrobe. But I can tell you it is diet rather than exercise that works best.
In any case anything to do with water is my bag, swimming, skiing, etc. etc.
I hate running but it is what it is.
This summer I have a nice 1.5 mile lake run 2 or 3 laps in the Bois de
Bologne. Very nice. Check out the this link to see my run.
It uses google maps so wait a minute for it to load and scroll down a little.
