One for the mathematicians:
Yesterday I did a workout on my Kickr Snap (wheel on) trainer. I used a different bike with a 2050mm wheel circumference. But the circumference in settings was in the previous wheel’s setting of 2150mm. So 10cm/10mm/4’ difference (less) depending on your measurement flavour.
What was my percentage difference in effort over a 45 minute ‘Birch’ endurance workout? And does that percentage denote I worked harder or made life easier?
