I ran it in 2014 and PR'ed. It's a great marathon, and well-run. Not a huge field but a great level of competition, thanks to Oregon's strong running community. Street parking 1/2 mile from the start was easy to find.

The course is not the world's most scenic but very nice. There are a few hills through mile 15 and then it's flat afterwards except for a corkscrew climb up to a footbridge around mile 21. Props to the Eugene French-American School for their awesome cheering section on top of that bridge... as a French speaker, I really got a boost from the much needed "Allez-y! Bon courage" at exactly that moment in the race.

Pretty much the only non-ideal part of the course is the mixed-use path around mile 21-25, where I've heard of minor altercations with cyclists and dog-walkers who get upset with having to make way for exhausted marathoners barreling through. There were a decent number of spectators in the first half and tons in the last mile, though it's sparse between 15 and 24. The aid stations were well-spaced and well-run.

Finishing in Hayward Field on the U of O campus is awesome, and the post-race recovery area has quite an extensive selection of food and drinks.
