出发前我就清楚这次旅行的严酷性——毕竟我以前就曾经这么干过——但是我体力上没有做好准备。

I knew, before I started, how rigorous the trip was going to be - I'd done it before, after all - but I was unprepared physically.

像往常一样，互联网提供了27个互相矛盾的说法。为了得到确切的答案，我给曾经帮助我取得签证的旅行社打了电话。

As ever the Internet supplied about 27 mutually conflicting reports, so to try to gain a definitive answer I telephoned the agency that had helped me with my visa application.
