Yes, that’s the beauty of Xert. Use the planner to give yourself a rough idea of how much training and what sort of sessions you need, then as the days go by it’ll adapt, so if you do more riding on your endurance rides your XSS requirements the following days will adjust. I try and stay on course for the Improvement Rate I’ve chosen, and I try and stick to the focus that Xata recommends, but depending on the time I have available I’ll choose a workout accordingly. So if I haven’t much time my endurance workout might be a bit more intense than traditional zone 2, conversely as it’s my day off on Friday this week and the weather is looking okay, I’ll ride easier for longer outdoors until I’m roughly in the ballpark for my XSS target, might even do a bit extra on Friday so I can have an easier day on Saturday. It’s this flexibility that cookie cutter one size fits all plans don’t have.
