Let me tell you about a race I ran on an unusually hot May day.
It was a 10 mile local race I love. I was feeling strong through the first half. Then I got to mile 7 and the water station was out of water.
Mile 7 of 10. On a hot day. Out of water.
Luckily I had my FlipBelt with bottles clipped in. I finished the race fine. But that experience cemented something I already believed — as a runner you cannot rely on anyone else to keep you hydrated. You have to take responsibility for your own hydration every single time you go out.
Here is exactly how I stay hydrated as a runner in summer.

Why Hydration Matters More After 50
After 50 our bodies become less efficient at regulating temperature and our thirst mechanism becomes less reliable. That means you can be significantly dehydrated before you actually feel thirsty — which is a dangerous combination for summer running.
Dehydration during a run affects your performance, your safety, and your recovery. Even mild dehydration — as little as 2% of your body weight in fluid loss — can meaningfully impair your running performance and your ability to think clearly. In summer heat that threshold comes faster than you expect.
The good news is that staying hydrated is completely manageable with the right strategy and the right products.
My Personal Hydration Strategy
I plan my routes near home. For most of my summer runs I plan routes that loop back near my house so I can grab water without having to carry everything with me from the start. Knowing there is cold water on my front porch waiting for me at mile 3 is both practical and motivating.
I leave water on my front porch. Simple and effective. A cold water bottle sitting on the porch ready to grab mid run is one of the easiest hydration strategies available. No fancy gear required.
I stash drinks on longer routes. For longer runs away from home I get creative. I have hidden Gatorades in specific spots along my regular routes — tucked behind a rock, left at a familiar landmark — so I always have hydration available when I need it. It sounds extreme but after 30 years of running I know exactly what my body needs on a long hot run and I plan accordingly.
I use my FlipBelt for races and longer efforts. The FlipBelt holds compatible water bottles right in the belt itself which means hands free hydration without a bulky vest. After the mile 7 water station incident at that 10 mile race I never run a race without my FlipBelt loaded with bottles. Ever.
What to Drink
Water The foundation of any hydration strategy. For runs under an hour in moderate temperatures water is usually sufficient. Cold water absorbs faster than warm water so keep it cold when you can.
Ultima Replenisher Electrolyte Powder For longer runs and hot weather workouts plain water is not always enough. When you sweat you lose electrolytes — sodium, potassium, magnesium — that plain water does not replace. Ultima Replenisher is my electrolyte powder of choice. Zero sugar, plant based, and packed with 6 electrolytes and minerals. The variety pack gives you multiple flavors so staying hydrated never feels repetitive. Mix it in your water bottle before you head out the door on hot days.
Nuun Hydration Tablets Nuun is a running community staple for good reason. These effervescent tablets dissolve in water and replace electrolytes without a lot of sugar or calories. The tubes are compact enough to tuck into a FlipBelt pocket or your running vest for on the go hydration during longer efforts. A reliable and convenient option that has been a runner favorite for years.
Huma Chia Energy Gels On longer summer runs when you need both hydration support and energy the Huma gel is my go-to. Made with real fruit and chia seeds they are stomach friendly — which matters even more in the heat when your digestive system is already under stress — and they provide a quick and effective energy boost without tasting like chemicals.
Gear That Helps
FlipBelt Classic Running Belt I cannot overstate how much the FlipBelt has changed my approach to race day and long run hydration. Compatible water bottles slide right into the belt and sit flush against your body without bouncing. After the race water station incident it has become non-negotiable gear for any run where water access is uncertain. I own two and I recommend it to every runner I know.

CamelBak Podium Water Bottle The CamelBak Podium is my water bottle of choice for training runs. The self sealing jet valve lets you drink quickly without spilling and it fits perfectly in the Peloton cup holder for post ride hydration too. Easy to carry, easy to drink from, and durable enough to hold up through years of daily use.
Practical Hydration Tips for Summer Running
Drink before you run. Do not wait until you are thirsty to start hydrating. Drink 16-20 ounces of water in the hour before a summer run so you start already hydrated.
Run early or late. The hottest part of the day is typically between 10am and 4pm. Early morning runs before the heat builds are significantly easier on your body and your hydration needs.
Slow down in the heat. Heat increases your perceived effort significantly. Running at your usual pace on a hot day puts more stress on your cardiovascular system than the same pace on a cool day. Slow down, reduce your expectations, and focus on finishing safely rather than hitting a time goal.
Know the signs of dehydration. Dark urine, headache, dizziness, cramping, and unusual fatigue during a run are all warning signs. If you experience these stop running, find shade, and drink water immediately.
Never rely solely on race water stations. As I learned at mile 7 of that 10 mile race water stations can run out. Always carry at least some hydration of your own on race day regardless of what the race organization promises.
The Bottom Line
Summer running is wonderful — the long daylight, the warm mornings, the energy that comes with the season. But it requires more intentional hydration than any other time of year.
Plan your routes, stash your drinks, carry your FlipBelt, and never trust a water station to have what you need when you need it.
Stay hydrated. Stay safe. Keep running.
