Trite as the saying is, the dose makes the poison.
Strychnine is similar to caffeine -- only orders of magnitude more potent, so that a couple of milligrams will stimulate your CNS, and a hundred milligrams will kill you. Caffeine, of course, will only stimulate you if you take more than about 100mg, and it'll only kill you if you take it by the teaspoon.
The strychnine derivative securinine (https://en.wikipedia.org/wiki/Securinine) was sold in Russia as a "safer" stimulant along the same lines as strychnine, until roughly the turn of the millennium. I enjoy experimenting with strange drugs -- and the Russian pharmacopoeia is as strange as it gets (the Italian one is also strange, with rubidium chloride as a stimulant!) -- so I've tracked down and tried securinine. Didn't notice much from it. Not much better than a strong cup of coffee. No discomfort, in any case.

Gatorade was invented in 1965, and the cross country shoe in the 70s. Prior to that it was the wild west, no one studied or knew anything about this stuff really prior to that.
They drank cold coca-cola that was defizzed every five miles, which surprisingly has good fuel as sugar with caffeine

2:30 marathon at 10,000 feet in August heat is pretty damn impressive given the poor shoe quality over 50 years ago.
So drinking water and a sip of cola is fine, but drinking cola against thirst has side effects as you need water to process lots of sugar.
Consuming plain water during really long endurance events can cause hyponatremia. Not recommended. But for the short 10k and under running events that most of us do, it doesn't really matter much.
And a ton of phosphoric acid.
