Staying Hydrated This Summer: It's Not About What You Drink — It's About the System

Written By Casey Katz

Everyone knows to water, electrolytes, sports drinks. The part that actually trips people up isn't the fluid — it's the logistics. Life gets busy, Friday night bleeds into Saturday morning, and your Long Run is here before you know it.

It Starts the Night Before

Hydration isn't a same-day decision — it's a plan. The night before any workout, take five minutes to think through three phases: pre-workout, during, and recovery.

  • Pre-workout: How much are you drinking before bed and again first thing in the morning? Lay out your bottle or hydration pack so it's filled and ready — not something you're scrambling to prep while you're already running late.

  • During: Where are you getting fluids mid-workout? Know your route, your stops, and what you're carrying before you walk out the door.

  • Recovery: Have something ready for the second you finish — a cold bottle in the car, a cooler waiting at home, or a drink prepped in the fridge. Recovery hydration works best when it starts immediately, not whenever you get around to it.

Planning all three phases the night before takes the guesswork (and the excuses) out of it.

Don't Underestimate the Cooler

A cooler is one of the most underrated pieces of hydration gear you own. Pack it the night before with cold drinks and ice, especially if:

  • You're meeting friends or a training group — bring enough for everyone, not just yourself

  • You're doing a workout that ends away from your car or house

  • You want recovery fluids to actually be cold and appealing when you're done, not lukewarm and easy to skip

A stocked cooler removes the last excuse between finishing a hot workout and actually rehydrating.

Route and Logistics Tips Worth Stealing

  • Plan your route around water fountains. Local parks are often loaded with them — map a route that passes a few, especially on long or hot days. This option also allows you to waste a bit of water on top of your head!

  • Stage water bottles along your route. Drop a few bottles in a cooler or tucked in the bushes at a halfway point before you head out, so you don't have to carry everything from the start.

  • Bring cash or a card in your belt for a gas station stop. A mid-run gas station detour for a cold drink (bonus points if they've got popsicles) is a completely legitimate hydration strategy.

  • Carry handhelds or wear a hydration pack if your route doesn't have reliable stops.

  • If you don't like carrying fluids at all, plan a 6–8 mile loop — something that takes about an hour — so you can swing back through home or your car to refill instead of running fully unsupported.

None of these are complicated. They just require five minutes of thought the night before instead of figuring it out mid-run.

Just Because You Can, Doesn't Mean You Should

Pushing through a workout dehydrated is often treated like a badge of toughness. It's not — it's a performance and health risk, and it's worth understanding why.

  • Performance drops fast. Losing as little as 2% of your body weight in fluid can noticeably impair endurance performance, and losses beyond that compound the effect — pace slows, perceived effort climbs, and your ability to regulate body temperature declines.

  • Your kidneys feel it too. Dehydration reduces blood volume, which means your kidneys are working with less fluid to filter waste and regulate electrolytes. Chronic under-hydration adds unnecessary strain to a system that's already working hard during exercise.

  • Dehydrated muscle is more injury-prone. Fluid loss affects muscle elasticity and how efficiently your muscles contract and recover mid-effort — a dehydrated muscle is a less resilient one, which raises the risk of strains and tears.

  • Recovery slows down. Rehydrating late means your body is playing catch-up on repairing tissue and clearing metabolic waste, on top of everything else recovery already has to do.

Toughing out a workout without enough fluid doesn't make you stronger — it just makes the workout less effective and the recovery slower. A little planning the night before goes a lot further than grit alone.

The bottom line: staying hydrated in summer isn't about willpower — it's about planning ahead, the night before, for every phase of your workout. Set the system up once, and the rest takes care of itself.
