Your what? The Steven Kruiswijk Coefficient is indicates how you used your training time. Did you take too many breaks? The longer the ride, the more minutes are allowed for a coffee, snickers of cola break. A 25 minute break in a 5 hour ride is fine, but in a 3 hour ride you would be taking it to easy.

Obviously, during a longer training, more time for short breaks is allowed. See the table in the next item.
