Staggered up the hill...

Here's the elevation profile of today's marathon:

I did it, but there was quite a bit of walking from 20 miles onwards! I'm not sure if it was "hitting the wall"; my legs felt reasonable but I felt quite faint. It was fairly hot and I had some cold, so I think that weakened me a bit.

First half was about 1:47, second half about 2:28, for a total of 4:15. A run of two halves!
