I've used electrolyte tabs in longer tris/marathons for a few seasons now. But I've never been sure how many I should take. I typically do about 3 before the start then 3-4 more about half-way through the race.
I'm wondering if there's a good, easy rule of thumb to determine how many e-tabs to use? I sweat a lot and hydrate well but am just wondering if I should be upping the e-tab intake, especially since my next race will be in the extreme west Texas heat.
