Oh, sure, I'm in reasonable nick: I'm used to lifting a 16kg weight, and carrying the same down the lane to school every day, but when I get tired, I put her down and she walks for herself. I also run up and down the stairs a fair bit, but I'd have to climb them forty times to match a 1,000' ascent - and there are no slippery rocks in my house, or scree.
During my July and October trips last year I spent the first three days feeling stiff and achy, and was only able to 'go for it' on the last few of days of each visit (two of which were written off by bad weather). This year, I had determined to get properly fit before I go.

I've also joined a local walking group - previously anathema to me - which is now forcing me out onto my local hills (the South Downs) at least once a week. I take the bricks too - for the entertainment of my fellow walkers if nothing else.
How do you get/keep fit for the hills?
