Sleep well two nights before your next big race!
In over 30+ years of racing, I have experienced restless sleep the night before my big race hundreds of times and still raced extremely well. WHY?
Because my Junior College Coach held us accountable to proper rest, healthy eating and hydration, purposeful workouts all the time. He also suggested getting great sleep and fuel two days prior to our races.
Let's be sure that two days prior to our races we have our favorite healthy foods and get to sleep on-time or maybe even 30 minutes earlier than normal.
And finally, don't go changing things. Don't suddenly carb-load, over-hydrate or anything that is super out of the norm.
