All rides.
Hearing loss is cumulative.
Earplugs are essential on long rides.
I rode home home from New Hampshire rally to North Carolina, in one day I think that was 800 miles with a roadster tank.
I rode home from the Michigan rally in one day, that was about 900 with an intestate tank.
I've done many 500 mile days, four in a row to the Utah rally. 500 mile days are pretty comfortable to me.
I'm 51 and have 2 small kids so I don't ride a whole lot anymore. Most of these rides were in my 30s and early 40s. All of them with clubman bars and rearsets.
With the intestate tank chain lubrication and adjustment becomes a limiter as far as miles you can do in a day.
I think it took me 20 hours to do 800 miles with the roadster tank, it was an ordeal
It was several hours less to do the 900 miles with the interstate tank. I think 16 hours or less. I I don't think an iron butt would be too bad with an interstate tank.
