What does this imply for race day? Pay additional consideration to consuming fluids within the days previous to your race and intention for 2-4 cups of water within the hours earlier than the beginning.

For runners coaching for occasions lasting greater than 60-90 minutes, that is notably vital.

On the subject of consuming earlier than a run, timing is sort of as vital as what you eat.

Meals excessive in fats, fibre, and protein take longer to digest than meals decrease in these vitamins. The nearer you get to the time of your run, the extra vital it turns into to eat meals that you would be able to digest and take in rapidly.
What does this imply for race day? Eat breakfast no later than 3 hours earlier than the beginning. Sure, this may imply getting up sooner than you had deliberate to. Take this additional time to stretch and get organized for the race, and even head again to mattress for a bit after. Having a smaller snack shortly earlier than race begin can even assist make sure you get some additional power with out filling up. Nice selections are a couple of sips of juice or ½ a banana.

Is there a technique that’s easiest so that you can undertake? Which one will you attempt first? I’d love to listen to your feedback.
