Having done it several times and volunteered at it once, here’s what I know:
It’s a fast course. Net downhill. No major uphills. There are a few hills, but nothing to get excited about. They are short, not very steerp, and by about mile 10 you are past the last of them of any significance. It’s a good race to try to qualify for Boston, as not too crowded, not too hot, and downhill.
The weather will not be hot. It also won’t be snow covered. December in Sacramento can be anywhere from 30’s rain and wind, to 60’s and sun. It’s common to be in the 40’s and foggy at the start, and warming to the mid/upper 50’s maybe low 60’s during the race. About every 3 years it seems to be a rainy and windy day.
The course is not the most scenic or destination. Not that it’s ugly, it’s just average. There are some residential areas, some strip mall type areas, and finishes in downtown Sac.
I really shouldn’t talk about the management, on the theory that if you don’t have anything nice to say… Let’s just say that after 27(?) years, they should have the book written on how to organize a marathon. When I volunteered a few years ago, they ran out of water at the mile 13 aid station (on not a hot day). And their recruitment methods for course marshalls was haphazard and unorganized at best.
On the positive side, they have experienced pace runners who attempt to run the race at an exact time. They will carry signs with their finish time, and try to pace themselves accordingly. They have pacers from 2:47 to 6:00 in 5-15 minute increments. This is a great tool if you are looking for a specific time.
Here’s a course hint if you do it: At around mile 24 the course zig’s and zags, passes under the freeway, and turns onto L street. L street has a pretty pronounced camber, so stay in the middle lane. It’s just long enough and late enough that hugging the edge to the finish can hurt the knees.
I’ll probably do it again this year. Kind of waiting til after Big Kahuna to see how I feel.
Good luck!
