I actually think this is a lot easier than doing an 100 mile ultramarathon
If all we want to compare is finishing an IM within designated cutoffs and finishing a 100 miler within designated cutoffs then yes. Finishing a 100 miler is much harder than an finishing an IM. Just stand at the finish line of an IM and see how many out of shape looking people finish, then stand at the finish line of a 100 miler and compare.
2x Deca-Ironman World Cup (10 Ironmans in 10 days), 2x Quintuple Ironman World Cup (5 Ironmans in 5 days), Ultraman, Ultra Marathoner, and I once did an Ironman.
