I don’t know the exact half way point by road, for the route I’m taking. However, time wise I have reached my half way point. Not because I’ve got half way through my available time, it’s more a case of crossing time zones.
I started my voyage in a distant land at GMT+10. As I head west I cross timezones going towards GMT. (Usually an hour at a time, sometimes 30 minutes). As we entered Kazakhstan yesterday the clocks went back, making local time GMT+5. Half way home!
