Where do you draw the line? (I know that the answer to that question is always 'somewhere') No one's getting significant levels of baking soda from their diet, and caffeine is a relatively recent cultural addition to most diets.

The gels are much the same. Getting the same nutiritional ratios used to require carefully controlled eating and certainly weighed vastly more than the gels adding both weight and complexity and likely being less performant.

Most(?) sports handle this by maintaining multiple leaderboards. The sub two hour 26.2 mile run was broken years ago, but the sub 2 marathon race was only recently completed, for instance. The difference being that the original was done much like this one in that it was paced, on a track, etc while the later was run in typical marathon conditions with other racers, variable winds etc.

Athletics has never maintained any sort of "leaderboard" for unsanctioned exhibitions. When Eliud Kipchoge ran a marathon-distance time trial sub 2 in 2019 it was an amazing feat of human performance but no one was under any illusions that it was a record.
