Too much salt?

[OakLeaf]

I've been a little stressed since, worrying about next time. Obviously, I have to hydrate, fuel, etc better than last time, so my usual should suffice, but I'm wondering if I need a little more, like maybe salt tabs beforehand as it's hot and the ride starts at 11.

Not sure what to do.

Pre-cooling gets a lot of ink. Normally I avoid AC like the plague, but sitting in a cold environment for an hour or so immediately before your ride can help. So can drinking crushed ice immediately before you go out. Are you already freezing your water bottles overnight? The more you can cool yourself internally, the less you have to rely on evaporative cooling and the less you will need to sweat.
