Yes! Ruined a few races this year experimenting and taking to much pre race. HR was through the roof even in the warm up
It can also cause you to go out too fast
Answer: Technically yes, but more so at slower paces. Some elites believe it is a kind of performance enhancing drug so I doubt it is slowing you down unless you are OD'ing if that's what you're worried about. People have different sensitivities and blah blah blah but even if heart rate is elevated from caffeine I highly doubt that would directly correlate with your lactic threshold and what not. People with blood sugar issues might have other considerations though. Short Answer is it doesn't really matter
Good question
Last I heard many years ago it was on the banned list but the minimal level allowed was raised to 2-3 cups.
My understanding is some endurance athletes do benefit.
It is a stimulant so I would guess yes, it does, but do not recall ever reading about that.
I might be ODing . 600mg a day

Increases HR but not RPE for a given pace.
I guess the world anti doping agency has allowed caffeine since 2004.
It is on the banned list for the NCAA.
The NCAA says it may help performance but to much can harm performance.
here is what AI says.
POTENTIAL RISKS • Caffeine is a banned substance by the NCAA. A urinary caffeine concentration exceeding 15 micrograms per milliliter (corresponding to ingesting about 500 milligrams, the equivalent of six to eight cups of brewed coffee, two to three hours before competition) results in a positive drug test.
Who were the first NCAA athletes to be tested for drugs?
answer in 1 minute.
AI did not answer the question.
Cross country runners 1986

As a former caffeine dependent, I began to doubt the wisdom of taking it less than an hour before a race since ny subjective feeling was that it raises body temperature slightly and thus has a negative effect on performance. I found that the best effects happened after 1 1/2 to 2 hours, making ne question whether we are better off without it?
Duh.
