I'm sure if I replicate last week in the next week or so I'll be able to get back to 15kg, which is my current goal.
UPDATE: I walked into work (1.5 hours +) and then walked after work (1.25 hours). My thinking is if I get in two walks a day, approaching 3 hours, 6 or 7 days a week, then I'm on the right track. I did have a flash lunch though, and when I got back from the office there was a full carton of piss sent to me by someone for free. These things are sent to try us, although, to be honest, I didn't really feel like a drink at lunch and didn't even think about it when I spotted the carton.
