Hydration Myths Runners Should Ignore
Hydration is essential, but misinformation can do more harm than good.
More water doesn’t always mean better hydration – especially for runners.
At Runplaygo, we’re committed to helping runners separate science from trend. Hydration advice is everywhere but much of it is outdated or oversimplified. This article busts the most common hydration myths that can sabotage your performance or recovery. Authored by Dr. Ramit Wadhwa, a consultant in non-invasive cardiology and an accomplished ultramarathoner, this article focuses on what really matters: timing, quantity, and quality of fluids for endurance athletes like you. Whether you’re a casual 5K runner or chasing a marathon PR, smarter hydration can make every mile count.
Sweating it out on the road doesn’t mean you should chug water non-stop. Hydration is about balance – too little leads to cramps and fatigue, too much causes bloating or even dangerous sodium dilution. The right hydration strategy enhances endurance, regulates temperature, and sharpens focus. The wrong one? It can slow you down or even put your health at risk. Let’s break the myths and build better habits.
Hydration Myths That Runners Should Stop Believing
- Myth 1: Drink as much water as possible
Truth: Overhydration can cause hyponatremia – a dangerous drop in blood sodium levels. Drink based on thirst and sweat loss. - Myth 2: If you’re not thirsty, you’re fine
Truth: Thirst isn’t always a reliable signal – especially during long runs. Pre-hydration and scheduled sipping matter. - Myth 3: Sports drinks are only for pros
Truth: Any runner training over 60-75 minutes benefits from electrolyte replacements, especially in heat. - Myth 4: Clear urine means you’re hydrated
Truth: Very pale urine may indicate overhydration. Aim for light yellow, not clear. - Myth 5: Caffeine dehydrates you
Truth: In moderate amounts, caffeinated drinks contribute to your fluid intake and may even enhance performance. 3-6 mg(1-3 cups of coffee) Caffeine per kg taken 30-60 min before exercise for maximal benefit .
