What to Eat During a Long Workout

(Without Feeling Heavy)

If you’ve ever hit the two-hour mark in a tennis match, pushed through mile five of a run, or realized halfway through a long hike that your legs suddenly feel empty — you’ve experienced glycogen depletion.

It’s not just fatigue.
It’s your body asking for fuel.

Mid-workout nutrition can make the difference between fading — or powering through strong.

Especially for women, fueling during longer sessions isn’t optional. It’s strategic.

When Do You Actually Need Food During Exercise?

Not every workout requires mid-session fuel.

For shorter workouts under 45 minutes:

Water and proper pre-workout nutrition are usually enough.

But for workouts lasting 90 minutes or more — especially in heat — your body is burning through stored carbohydrates.

This includes:

  • 3-set tennis matches (with deuces and tie-breaks)
  • Long pickleball tournaments
  • 5K/10K races
  • Long cycling sessions
  • Hiking or walking for 2+ hours

At that point, electrolytes alone may not be enough.
You need carbohydrates.


The Goal: Light, Quick, Easy-to-Digest Fuel

You don’t want:

  • Heavy protein
  • High fat foods
  • Large meals
  • Energy bars loaded with fillers

You want small amounts of real food that digest quickly and keep your blood sugar steady.


Best Whole-Food Options During a Long Workout

These are simple, portable, and effective:

  • A banana
  • A few dates
  • Orange slices
  • Homemade energy bites (oats + nut butter)
  • A small handful of dried fruit

These foods provide quick, usable carbohydrates without artificial ingredients or gut disrupting additives.

For tennis specifically: A banana between sets can stabilize energy and prevent that shaky, drained feeling late in a match.

For runners and cyclists: A few dates or orange slices every 30–45 minutes can help maintain steady output without feeling heavy.


What Not to Eat Mid-Workout

Avoid foods that:

  • Sit heavily in your stomach
  • Contain artificial sweeteners
  • Combine high fat + high sugar
  • Include long ingredient lists

Ultra-processed “energy” snacks can cause blood sugar spikes followed by crashes — exactly what you don’t want during endurance activity.

Mid-workout fueling should feel light, not complicated.


Electrolytes vs Food: When You Need Both

Electrolytes replace what you lose through sweat:

  • Sodium
  • Potassium
  • Small amounts of magnesium

But electrolytes don’t replace glycogen.

If your session is:

Under 60 minutes → electrolytes may be enough.
Over 90 minutes → combine electrolytes with small amounts of whole-food carbohydrates.

That’s the sweet spot for sustained energy.

For longer sessions, choosing clean electrolytes matters. Look for options that contain sodium and potassium without artificial sweeteners or synthetic additives. CocoBana™ was created to provide simple, real-food hydration — powered by coconut water, banana, sea salt, lemon, and marine magnesium — in a portable, easy-to-use form.


A Real-Life 3-Set Match Strategy

For longer tennis matches:

  • Hydrate consistently from the start
  • Use electrolytes early — not only when you feel tired
  • Eat a banana or dates after the first set if it’s competitive
  • Don’t wait until you’re depleted

Small, proactive fueling prevents the late-match energy crash.


Why This Matters More for Women

Women often under-fuel during workouts.

We’re taught to:
“Push through.”
“Burn calories.”
“Earn our food.”

But under-fueling leads to:

  • Increased fatigue
  • Slower recovery
  • Hormonal stress
  • Muscle tightness

Fueling during long workouts isn’t indulgent.
It’s intelligent.


The Bottom Line

For longer workouts, especially over 90 minutes:
✔ Hydrate early
✔ Use electrolytes strategically
✔ Add small amounts of whole-food carbohydrates
✔ Keep it light
✔ Stay ahead of depletion

Strong performance doesn’t happen by accident.
It happens by fueling with intention.

Nourish your body.
Hydrate Healthy.
You’ve Got This.
