Scheveningen to Noordwijk

After a few weeks hiatus, I resumed my training for the Nijmegen Vierdaagse today with a walk through the dunes from Scheveningen to Noordwijk, about 20.5km.

The weather wasn't ideal - muggy and overcast, and about halfway into the walk, very rainy.  For the sake of experimentation (and because I hadn't charged up my GPS watch) I only used the iPhone (with the MapMyRun app) to record the route... very effective, but it also drained the battery very fast, so I stopped recording at Katwijk.  By the time I arrived in Noordwijk and wanted to look up the bus information, the battery was completely dead.  Not the smartest idea, thus.
