How can you have two rides of equal duration (50 minutes), both indoors on a trainer using the exact same equipment, where you go farther (i.e. faster) on one, yet produce fewer Kilojoules (i.e. less work)? Here are the particulars:
Jan 24- 12.8 miles, Avg power 127, Normalized power 165.... 413 Kj
Feb 2- 13.3 miles, Avg power 136, Normalized power 149.... 408 Kj
Jan 24 ride was a series of 1-minute intervals
Feb 2 ride was a set of 5 minute intervals.
Perhaps I do not understand Kilojoules... can someone please clarify?
