Distance Learning

Something's not right. I seem to be falling short and I don't know why. I knew there was an issue but now that I retread old ground it has become more obvious. I can't do the distance any more. And I don't know why.

I came this way 9 years ago, specifically Charleville-Meziere to Verdun. Don't look it up, just trust me. It's a distance of about 110km. Back then I did it no problem and arrived in time for tea. Now I find 80km a challenge. 

Of course, it may be that I am going in the opposite direction, against the prevailing winds and the hills seem to have got steeper. Plus now I am camping, so no quick getaway. 

But something tells me that there is another factor at play. If only I could figure out what it was.
