The grand total of 490 extra calories apparently. Pretty disappointing considering I walked almost 9 miles 
That's about the distance we had to walk for our sponsored walk at school, and the teachers encouraged us to buy 'extra' chocolate at the tuck shop halfway round 'for energy' fundraising... We all ate more than we burned 
Anyway, I ache today (not used to working those muscle groups that much I guess) so no walking at all for me today! Anyone else been disappointed seeing the reality of calorie burn after feeling like you worked really hard for it?
