Any recommendations for electrolytes?

Precision hydration

Make your own. Squeeze a full lemon, add a sea salt with at least 8% trace mineral content. If you really want to soup it up, and potassium chloride and a squirt of 40,000 volts. You can even turn it into a sports drink by adding maple syrup. All this for pennies on the dollar and enjoy a superior product for your efforts.

Don't waste your money. The body of evidence refuting the idea that electrolyte supplementation is beneficial for running performance is much stronger than the paltry amount of low-quality evidence that it might help, much of which has been funded by very biased sources such as the Gatorade Sport Science Institute. Tim Noakes is a rather problematic individual in other capacities, but he's carried out some of the highest quality work on hydration and electrolyte supplementation, and it seems pretty clear from the large body of work he's produced that the electrolyte industry is a sham. (For what it's worth, I'm an assistant prof at a world top-20 university in a relevant field, and I've actually read the original academic publications critically).

Eat real food buddy

I do the same. Just drink salt water. It's cheap and there are no calories. You can also add magnesium powder if you wish.

Salt is very important for endurance athletes, especially in hot weather. You don't need to pay for a sugary electrolyte drink, but distance runners should absolutely be consuming salt, lots of it. There are many academic peer-reviewed publications to back up what I'm saying. Let me know if you want citations.

Ur just throwing your money away. Dang

Huma makes gels with electrolytes. They are very good and I mix them into my run nutrition when it’s very hot as I suffer badly with electrolyte imbalance.

I believe they have more electrolytes than other brands last time I checked on the feed.

Gatorade Endurance. As a long distance runner in the HOT and HUMID south of Louisiana Gatorade Endurance has always kept me afloat. Training during the summer for a Fall marathon often finds oneself dumping 3 pints (48 oz. weight or volume) of sweat every 6 miles. It's not unusual to have conditions of 85 to 105°F and 95% humidity from May thru August as early as 4:00 am. I personally hitting the road at 4:30 am while the temp is at 85 or a tad below. Most marathons stock their watering stations with Gatorade Endurance.

Loss and proper replenishment of electrolytes is a most common detriment to a successful marathon or any other long run.

What this guy said.

A single lemon has about 90mg of potassium, and around 5mg magnesium.

Add some salt and some raw sugar and you've got yourself a fairly gut-friendly sports drink (and for a fraction of the price).
