My understanding is that the major benefit of travel partner pairings is that other schools can visit both of the schools in one weekend (for non-football sports). For example, a school could fly into Eugene/Portland and play Oregon on Saturday, then ride a bus to Seattle to play Washington on Sunday, then fly back home Sunday night.

What is the upper limit for this type of relationship? Bus drivers are legally capped at 10 hours of driving per day which roughly translates to 600 miles. Is that the upper limit or are there other factors which would make even 600 miles too far for a travel partner pairing?

Edit: I found an interesting article/analysis on the travel partner pairings for the Sun Belt and C-USA as of 2019 (Evaluating the Two-Game Road Trip in College Sports). I've compiled the approximate distances for each pairing referenced in the article. These distances are based on the first route that Google Maps recommends for each university pairing. It looks like the median distance for these pairings is 209 miles.
