You may have seen the site
http://www.sundaymorningrides.com. Its a new website for posting and sharing rides, their maps and GPS files. Its pretty cool.
Out of curiousity, I wrote them about posting longer rides, and they enthusiasticly responded.
They have added a "Long Distance" section to the site. It currently has only one listed ride (mine), but they'll be happy to post more.
Check out the instructions for submitting. I just sent a mapsource file, gpx file, a few photos and a ride report.
This could be great spot to share saddlesore, Bunburner and other IBA rides and ideas.
I have no affiliation with the site - I just like it!
