No Marathon Weekend for me this year (it's tough for my wife to get the time off) so I registered months ago for California International.
It's net downhill, but I recorded 620 feet of elevation gain on my Garmin due to the rolling hills.
I PR'd because I didn't go out and blow up as I did for the marathon weekend this January. Stayed with the 5:50 pacers who did a 2:00/1:00 run walk split, and finished 30 seconds ahead of that pace.
As races go, it's well run and geared towards faster runners. (It was the USATF nationals this year.)
Most of the corralls were for increments between 2:hr and 4:30... I was in the 4:30 and above. Self-selected corralls for 10k runners, but a 6-lane wide start mile and no places on the course where they're really restricted for width. As a pace group, we were probably more of a hazard to navigation than other runners.
It's mandatory bussing to the start line, as it's a point to point and the City of Folsom is picky about security at Folsom Dam (adjacent to the start). I drove from home, got to Sacrament at 3:45, parked near the finish, and walked to the bus pickup, which closed (there) at 4:30), so I used the porta potty, but you get to get back on the warm bus while you wait!
Depending on marathon weekend 27, I'll probably sign up again next year.
