I say yes really.
Maybe somewhat true for PE and relative heart rate. I think that heart rate is a good measure, but also affected moreso by heat/dehydration, etc. that other metrics might be.
%FTP whether bike or run is lower for slower athletes. It's more time based than speed based. An athlete who rides 4:15 for an IM might be able to go 75-80% FTP. An athlete who rides 6 hours will be less maybe 70% more or less. And depending on the relative fitness of the athlete, the %age might be higher or lower.
Sure, slower athletes can ride 80% of FTP for longer, and they'll walk most of the run. But, a targeted bike FTP of <70% might be a better strategy for a less fast athlete. That 10ish % difference does make a difference in digestion I think. Some solids, ok I think, especially if it keep hunger away. I think that primarily liquid nutrition is the 'safest' way to go...N=1s for solids excepted, if that makes sense.
Edit to add. I generally lump blocks and gels into the liquid category.

I just assume that fast guys are (generally) doing IMs at the same perceived exhaustion/HR relative to as slower guys, they are just doing it...fasterMaybe somewhat true for PE and relative heart rate.
