Hardest Pool Event?

I always find myself in the most amount of pain after a 400 IM and consider that the hardest pool event. What events do you think are the hardest?

Parents
  • 400 IM is rough.  Each transition is pain in addition to the individual 100s.  Non meet events: An hour postal is rough if you go straight and push it.
