Stay healthy before your big race

A:

Prioritze recovery

First of all, you want to make sure that you're prioritizing your recovery as much as you're prioritizing your training.
Make sure you're getting adequate sleep well before the marathon. Most people are going to be pretty nervous the day before a race, so you want to make sure you get your sleep leading into race day. 

Mobilization exercises

You also want to make sure that you're doing your mobilization exercises all the time. Work on your hips, your glutes, your low back, your thoracic spine, your ankles and your calves. 

Hydration and nutrition

You want to think about your hydration and your nutrition leading up to the race. Even while you're doing your practice runs, thinking about what you're drinking and how much of it you're drinking while you're running is important. Also think about what are you eating before you're running.

Keep that routine as you're going into race day because you don't want to change anything up too close to your race. You also want to make sure that you're not trying anything new on race day so that don't you upset your stomach during the race.

Listen to your body

And last but not least, one of my biggest tips is listening to your body. 

If you're feeling unusually fatigued, you've got persistent pain that's not going away or your performance has decreased, chances are you're probably not recovering enough. Take that extra time to recover before the big day.
