I am an Ironbutt Motorcycle Rider. There are a number of Ironbutt rides, as well as an 11 day rally that covers around 11,000 miles. I have completed the Saddle Sore, which is 1000 miles in under 24 hours, and a Bun Burner which is 1500 miles in under 36 hours.
I have done a few centuries on bikes, and I would say to compare the two, when I am done with a Century I am physically spent (hungry, thursty, legs weak). When I am done with 1000 miles in about 18 hours, my butt hurts more (even with my custom Corbin seat), my body is stiff, and I am much more mentally drained.
The big difference with the 2 is that there are motorcycle riders that all they do is commute and do weekend riding, and decide on a good day that they are going to do a Saddle sore. They'd be real sore for a few days after, but it is doable. There is no average bicycle rider riding 10 miles a day, a couple times a week that is just going to do a century. You have to train for it, and while training for it your butt gets used to being in the saddle.
Which is the true Ironbutt, go do both and you decide,
