That's kind of an interesting one: I'm remembering how it felt to be at week 4 and nervy all of a sudden! But I am doing this sientries.co.uk/event.php?e... in September, and I'm doing it as a runner not a walker, so I'd better get myself ready to run the thing. Eeeeek!
And on doctors' orders (long and basically non-health-related and therefor really annoying but there we are) I've also got to try and gain half a stone, which is a bit tricky when you factor in runs (eating nearly 3000 calories in one day to compensate is not fun), BUT I've gained 3lbs and am pretty pleased with that too.
Tips for high calorie non-hideous run-friendly food are really welcome, by the way. I am drinking so much whole milk I'll be mooing soon!
