I also sweat like crazy and rely on both electrolyte drinks and Saltstick tablets, and occasionally pickle juice to keep from cramping early. But I still end up cramping and it's always in the same order (right calf, left calf, then everything else).
Been doing hot weather runs lately, because In mid-August, I'll be pacing a friend at the upcoming Habanero 100. She's doing the 100-Miler, and I'm going to likely pace the last three loops for her. I paced 40 miles for her at this year's Rocky Raccoon 100-Miler (and she finished in under the 30 hour limit, her first 100-mile race/attempt) so I'm excited to be part of her team again.
But this insanely hot weather is going to make this really rough I think.
Consistency: It's only a virtue if you're not a screw-up.
