I live in the Chilterns in the UK and have used TR on and off for a couple of years. I have successfully built from zero using TR twice each time with great results (based upon Strava effort comparisons!).
I’m a self confessed numbers geek, but use them to reference myself rather than to compete against others. I use a dumb turbo trainer with a left-crank power meter.
Looking forward to a big 2020 with Amstel Gold, Black Rat Sportive, Dragon Ride and Etape du Tour currently lined up.
