Yes, but there were some aspects that I found a bit hard to really believe. Such as carrying a pack that she could hardly lift up and a fit young fella struggled to lift. Also walking for days with lots of blisters. I wonder if there wasn't a bit of exaggeration, given that something like 10 years had elapsed before she wrote it.
Also got sick of reading some of the non walk bits. Didn't much like the chapters where she skipped off with some bloke she met at a pub.
