Put in a solid effort on the trainer after work today, completing a steady state effort of 5 sets of 8 minute intervals. This workout is the bread and butter of my training regimen. I have a few variations for interval length, but my watts are very consistent. It's a lot easier to do these indoors on a trainer vs. outdoors in that the efforts are more controlled. The workout itself isn't easy at all, but I've grown used to them. It helps me stay at race pace for longer.
