The best part is access to heart rate average while in the Tour de France. These guys average about 130bpm for most of the days with only shorts spikes (8-11 min) at above 170bpm. It's a total jogfest at the elite level. Check out science of sport for more,

If serious, I'm amused.
Yes, cycling has lots of places where you go along fairly easy. But it's different from a jog fest, it's like doing 5 or 6 steps at 11s 100m pace and then going back to 12 min pace. Easy, but gradually weakens the edge.
But of course the hard parts are hard. You might only get the HR spiked way up there at certain points, but usually at that point it's a massive dig just to hang on. It's like going along pretty easy for an hour then you race a surgy 5k. Then along easy for an hour, then abother surgy 3k. Some more easier stuff. Then another 5k. Short recovery. Then 4 min as hard as you can.
Mountain days are a little different. Those can often be more like easy running interspersed with 10-60 mins running around marathon effort. So think like 10 miles easy, then 8 miles MP, jog 4 miles, 6 miles MP, jog 5 miles, 10 miles MP, jog 8 miles, 7 miles MP, jog 3 miles, 5 miles MP, jog 3 miles, then 15km race pace for 30'. Keep in mind that all of this isn't necessarily steady running, on the descent stuff it's all sprint interspersed with barely pedaling, and on flats it's similar but more light pedaling with quick surges and short sprints. The MP efforts are different too, because it's like racing where instead of running straight 3:00km you run 11s 100m, 14 s next 100m, then go 2:35 for the next 800 before doing it again.
Whether that's "harder" than running is a bit silly to speculate on, but cycling is incredibly taxing in its own way. In some ways I'd say it's more mentallybdifficult because you just have to be mentally present he whole time, not paying attention and you can lose the race in 5s. Imagine an ultra where at any point you're competitors can start sprinting and if you don't start sprinting then you automatically lose...that's bike racing sometimes. If someone sprints at mile 5 of a marathon it's not a big deal if you don't react for 10s, or even elect to go with the move.
