I've invented a new syndrome.

Post Audax Weight Gain Syndrome.
I'm 1kg heavier (as of last night) than a week ago. But my body fat (as measured by Tanita scales) is down from 17% to just under 16%.
I think Chris has it right - increased fluid in the leg muscles. I've not got any fatter round the waist afaict.
Will see if it renormalises over the next few days. Gym reckon I don't want to go below 15% because of the ultra endurance nature of Audax as having those reserves will be useful.
Of course, those scales can't give an accurate absolute reading and can only really indicate the direction of a trend. I want to get in one of those body fat pods I saw on the telly.
Life Measurement, Inc. BOD PODHowever, I did find some negative stuff about accuracy of that too. They have one at Addenbrooke's apparently.
