My typical weekend of riding ( if there is such a thing) consists of a longer ride with a lot of climbing, and a shorter, more structured workout centered around a series of higher intensity repeats, ranging from 5 to 20 minute intervals. Longer days are around 5 hours schedule permitting, and the higher intensity days around 2 to 2 1/2. On the long days I don't necessarily go easy, just a nice tempo pace such that when I get home, I have pretty much drained the tank. Press the hills fairly hard and stay low/mid zone 3 the rest of the time.
It is easier schedule-wise to do the long ride on Saturday mornings - I can leave the house at sunrise and still have the bulk of the day after riding for chores and the rest of life. However, I feel the miles in my legs on Sunday afternoon doing the reps - don't feel like I can generate the same power. The perceived intensity is the same, I just don't have the gas to go as hard as when I do them on Saturday morning.
So I am wondering how much training benefit I may be giving up by doing the hard reps when I am tired. I only race occasionally, though I do take the training fairly seriously.
How do others sequence their weekend workouts on non-race weekends?
