Yesterday I went on a 60-mile ride on a very hilly route. No long mountain climbs but it was essentially a climb, recovery descent, climb again and nonstop.

I had a large bagel for breakfast and some orange juice. During the ride I ate one packet of Shot Bloks and towards the final third of my route I had a Nature's Valley Oat and Nut granola bar. I never really felt hungry at any point so I ate little.

For hydration I had one large water bottle filled with Clif Shot electrolyte drink and another bottle with just water. I drank quite a bit of water and even stopped to refill it once, but attempted to make the electrolyte drink last the entire ride.

During the final 5-10 miles of my ride I experienced bad cramping in my legs. I can take any amount of pain and burn, but a cramped muscle just about locks my leg movement completely. I wasn't even really burning or hurting that much, but it seems the cramps came on easily.

At the end of the ride when I dried off the salt was so thick it was like white powder on my skin. How much salt loss through sweat is normal?


Did I take in too much water and too little electrolytes? I assume this is what probably caused my cramping towards the end. I've seen little tablets you dissolve in your water to create an electrolyte solution. Aside from the regular drinks, what else is good for electrolyte replenishment?

Yes, you needed more salt. Did you do the entire 60-mile ride with just two bottles? On a ride like that, I would've been drinking a lot of water/gatorade/powerade before the ride, my two bottles by the 30 mile mark, a bottle of water/gatorade at the 30 mile rest stop, and finished my refilled bottles by the end of the ride whereupon I would've drank the two bottles of water/recovery drink stored in my truck.

On a recent century I actually carried a baggie with some coarse sea salt in it. That came in handy as the gatorade at the rest stops was severely watered down and by itself probably didn't have enough salt to help me anyways.

V-8 has 40% of your daily sodium intake; I prefer the spicy kind. On group rides, a number of riders get that.

On a hot day, you can sweat a LOT of salt so be sure to be well hydrated and drink plenty.

At the end of the ride when I dried off the salt was so thick it was like white powder on my skin. How much salt loss through sweat is normal?Depending upon how much you were sweating, about 300-1000 mg/hr of salt is sweated away. The recommended daily intake of sodium is actually too low depending upon how much you ride. I've settled on taking in 500mg sodium per hour as a general rule.
