The same is true for the kilo, Elites and some age group masters race the kilo while masters 50+ race the 500 meters.
I would assume all of it is hard if doing it right!
I guess the 3k is why perhaps pursuit interval time for a workout is often 4min?
Wish I could try pursuit. Seems up my alley.
I sometimes pretend to do 4km outdoors for funsies to mix up riding the TT bike. I cheat and use a false flat downhill so the speed is on up there. Haha!
