The RD for the OD100 mailed out the detailed splits a week ago for this year’s race.  I don’t think pace charts work too well for 100-mile races due to the variability of terrain and the inevitable lows that you go through.  Hopefully, these can provide a guideline as to times you can expect to reach certain aid stations.  I’ve used my time for the 24 hour pace and then added in the splits for the winner and last person to cross the finish line.

It’s interesting to note that there’s not much difference in paces early on (2-3 minutes from fastest to slowest), however huge gaps at the end.  Guess you never really know so buyer beware.
