To white line or not ...
More on pace lines
Should you ride the white line or stay to left of it or to the right?
If it's wet, never ride the painted lines.
If there is as much as 2ft or more to the right, then ride to the right of it.
Otherwise, ride where it is the smoothest! A smooth ride for the pace line is always preferable than worrying about anything else. The lead of the pace line needs to pick out the smoothest path forward. Always.
