from personal experience the right combination of pot and stimulants would in the mid 2000s would give me enough motivation to ride my bike 50-100km over a weekend (I then rode a traditional British touring bike- this was before the modern e-bikes were invented).
I quite often used the same routes to get to places like raves that “normal” cyclists did and there would be a mixture of “fast” types on their racers with all the gear and “social” riders.
I took to cycling later in life than most pro riders so I never considered myself good or “clean living” enough for racing (though probably was no worse than many competitive riders) and didn’t push myself that hard as I also needed some energy for the rave when I got there but was usually in the faster 33% of this group.
IMO not impossible that someone motivated enough who balances the THC levels etc (like the article suggests) may indeed gain some benefit from cannabis as once they have started riding or doing their other exercise it can itself be pleasurable like taking drugs.
