So I survived all 42.195 km of the Duesseldorf marathon. Evidence can be found here:

Many thanks to Torsten and Christiane for the photos - and for taking such good care of us - Danke schoen!!

Now I'm back at home, trying to figure out how to catch up on my work
and entertain all the visitors flocking to Cambridge to visit... I'm
thankful for friends, but where to put them all?? Not to mention
getting back into rowing and trying to finagle a tourist visa out of
the Russian consulate... I'm sure it will all come together
somehow.  (I can't annul God's watch-care over me by
over-extending myself, can I?)
