It was the exact same ride I did last sunday. I felt more tired today. That I had a hangover and was riding in 4pm sun didn’t help. Anyway, 68kilometers in 2:30. My device says I did 1396 kilohoules (kJ) of work today and 1365 kJ last week. That number doesn’t mean much too me — what is the significance of having burnt and extra 31kJ today.

It’s either 0.83 x metabolic energy of one gram of fat or 1.8 x the metabolic energy of one gram of sugar or protein.

That is, today’s ride burnt an extra half-packet of sugar. Fantastic.
