Congrats on your IronButt ride !
What an accomplishment !!
I do know... Many years ago I was a factory rider for a major builder road testing models prior to their release to the public.
Our duty was to put 300 miles on the odo in an 8 hour shift,
With a 1/2 hour lunch break, and two 10 minute pit stops per shift, it was a difficult task.
We were asked to do a representative mix of city and highway riding, legally, obeying all speed limits.
It was not possible to do so.
I have never participated in an endurance run, nor would I want to.
I very much enjoy the ability to quickly stop to investigate interesting things along the way.
lol I hate trains ! Too many missed opportunities !
Best
