Well, we didn't walk 5km, but we did do a good hour of walking round various points of interest.
I ate pretty well. Have honestly logged everything and am 40 calories over my goal - which while annoying, is (again, taking positives from everything) far better than I would've been in the bad old days. Weirdly enough, if I'd not told MFP i was at the gym 3 x a week, I'd only be 20 calories over 
Good points:
We went to Frankie and Benny's, and I chose healthy options, spaghetti oceana and mango sorbet, although did have a glass of red wine.
Bad Points:
I didn't eat before I left home, and ended up eating a pretzel from Tesco for breakfast, and had some Aero bubbles in the afternoon. What did I learn? I don't really like Tesco's salted pretzels from the bakery, so I won't do that again!
Must remember to eat before leaving home.
Must do better tomorrow.
Tomorrow is a new day.
Still proud that I ate out, with someone eating pizza and ice cream (ironic, no?) in front of me, yet I STILL had the healthy option.
So today's snacking was a blip. At home til silly o'clock tomorrow afternoon, then out for the evening so will eat extra healthy just in case I end up eating out again.
