The original route was about 3500 miles over 15 days.
I ended up doing 4200 miles in 13 days.
Partially because my original plans had me staying in Sturgis 2 days
when I ended up staying about 2 hours .... (more on that later)
Also ... on some of the days I simply wanted to go farther .. cause I was having fun
other days I was forced to stop due to weather (rain, heat, etc)
THe days were (roughly) split up as far as miles per day
