Exactly, by having it finish roughly at the same time as the 200km ride. I did enjoy that early morning 100km blat (despite the rain).
Me too, I was first back to base, chasing a group of imaginary riders.
They'd dropped me -- somewhat rudely I felt (having dragged them across the Marsh in the wind) -- when I stopped to examine a rubbing brake pad. So I committed to chasing them down before Tenterden. Only, they'd missed the turning for the Smallhythe road and carried on along the main drag.
What an excellent road that is over Oxney.
Things went rapidly downhill after that, with 3 (three!) punctures...
