I’d like to try a 100TT but the logistics don’t really suit me, and if I recall correctly in the U.K. it’s open roads in normal traffic which doesn’t really appeal.
But it would be interesting to see what my time is on a relatively straight/flat route for the ton. I’ve only done a few 10TTs, unofficial best 24:45 which is good for FTP verification not so good for IM calibration.
