Assuming you have a coach or a plan, follow it! For my athletes we have a few key days to raise fitness but the rest of the days are about recovery and maximizing those big days. Saturday we have a race simulation that is one of the hardest workouts I do, and I will be doing, alongside my athletes. The key to nailing that workout is following the plan this week. Sure there are a few hard sessions, but the rest are recovery. Do the easy days easy so the hard days can be hard!
Riding a recovery ride at 80% because you feel good is not the way to hit 100% on Saturday! It may be time to tune out social media, if you see others posting epic sessions and you are wondering "should I?" Again, #followtheplan
