On hot, humid summer days, I take an Endurolyte capsule before a ride, after each hour of riding, and when I finish my ride. So far, cramping has been eliminated for me. However, results may vary with each individual.
I borrowed Endurolyte capsules from a friend to finish a ride when my legs were cramping so severely I had previously stopped pedaling. I now use them on all rides over 4 hours to prevent leg cramps.
My husband is nearly 60 and he is a Land Survivor works outside year round on all types of terrain and all kinds of weather. He often relies on his endurolytes capsules to replenish what he's depleted while working hard. They help tremendously to prevent or help alleviate cramping and muscle spasms during the night. We by them 2 or 3 bottles at a time. I've used them too and recommend them to anyone who suffers from muscle cramps, spasms or Charley-Horse pains. And by the way, they work very fast!
I started using Endurolytes after a bad leg cramping episode on a metric ride a few years ago. I've since started using them for all rides over 35 miles and after intense trainer & indoor rowing workouts. Electrolyte maintenance is important for endurance efforts.
First tried these during the Horribly Hilly 100 ride in Wisconsin in the summer. Although it is difficult to prove these work, when I use them during a tough hot ride I dont get cramps. Thats good enough for me.
I rely on Hammer Endurolytes to help me cope with Sonoran Desert heat. I work diligently at hydration to avoid cramps, but my insurance is this product. I use it to replace electrolytes on rides longer than two hours when the temperature is high. We have many triple-digit temperature days, I leave early to ride, but the bike computer still shows the temperature when I am riding goes above 100 degrees regularly.
Endurolytes are an excellent means of maintaining electrolite levels to avoid reduced performance or cramps. I always have some either in my jersey pocket or in my hydration pack during long rides. My wife uses them regularly for restless leg.
I live in an area with very hot, humid summers and often suffer bad post-workout headaches and muscle cramps. I started taking Endurolytes before and after rides, and sometimes before bed on really hot days. I feel noticeably less crummy after hard rides, and the headaches have gone away. If you sweat a lot, I strongly recommend Endurolytes or some other comparable electrolyte supplement.
