PreLoading Electrolytes

[Miranda]

Have any of you ever had any ill effects from pre-loading electrolytes on a ride?

This link goes to an article on a website of a sports drink I use. E-lyte Sport. The article is about the practice of "pre-loading" a concentrated level of the drink, like a shot, before your ride, vs. diluting it. I have only used it diluted post ride so far....

The only negative I can see is if you have kidney issues etc. medically. Which far as I know, I do not.

I'm just curious is there is such a thing as "too much salt intake" on a hard ride? Like could it cause not the correct amount of perspiration etc.? Maybe like the *opposite* of bonking from lack of water and food etc.?

Here's the ride deal...

Tomorrow if I feel up to it, I plan to do my furthest ride I've done so far in prep for my century (& furthest miles ever thus far since riding). 40+mi w/climbing (out alone). The temp forecasted is 90 degrees F and 80-ish% humidity...

I just don't think plain H2O is going to cut it.

Btw, I do plan to try and leave earlier in the morning, vs dead heat of the day.

On the miles... I did part of the same route w/in the last couple weeks for 34mi. But, it was 70degreesF w/low humidity. I was tired, but not "spent" after the ride.

Following the article here on TE re: "...how to increase you miles for 1st century"... I don't think 40-ish is unreasonable.

It's just the weather... and I don't want a "good drink thing" to turn out to be a "bad thing".

TYIA.
