Odd distances
The Oregon Mid-Valley Road Race, in Albany OR, offers events of 5.2 miles and 3.75 miles.
The unusual distances aren't due to poor measurement. The scenery and course, organizers will tell you, are the reason to run, not the specific distances.
While it's usually best to stick to standard distances (even those infrequently available, like 12k or 15k), if you have an unusual course, runners may appreciate something different.
It also helps to produce a race like this at the end of the year. Runners may treat it as an "off-season" event and display a greater willingness to vary from their traditional racing standards.
