H2O on the H1200?

I packed my bike and gear for the Hokkaido 1200 on Monday night.  Off on Wednesday morning for a 9PM start from Sapporo.  Ready to go.

Meanwhile a major typhoon is approaching west Japan and will be much closer by Thursday.  We will definitely catch a bit of rain and maybe a bit of wind on the H1200.  What would a 1200 km randonee be without some rain?  Boring.  And we need to remember that wind and rain give Jerome and me an advantage over skinnier Japanese riders.
