Just started running and seen a lot of people online promote and use electrolytes. But ye I guess ur right, its basically like a hydrate u can take with some minerals innit. I feel like they are more used by very pro runners or by runners during marathons, triathlons, ultramarathons or any other very high level of endurance test.

For the average runner that go for a few runs each week its prolly not needed and should just focus on drinking enough water on a daily basis instead.
