I have run this race for several years. I think it says something because I live nearly 450 miles away and load my family into the car to make the drive.
This year, there were some challenges with the train schedule that caused issues for the later races. This caused some confusion for many people, including a veteran like me, since the order of the races was changed as well.
Since I'm traveling so much to this race, I don't just run one 5K, I run them all: the all day 20K lets you run the course 4 times with all the different age groups, which is like running nearly a half marathon, stopping each 3.1 miles to stretch and listen to the Star-Spangled Banner. As long as you can run fast enough to make it to the finish and then back to the starting line on time, this is a lot of fun. These days, the schedule is more approachable to those of us who are not really fast.
It is a simple course, with very little elevation change, and you get to run alongside the beautiful Pacific Ocean for part of it. Oh, and the last quarter mile is DOWNHILL!
I like it that they have 4 separate races for "normal people," spaced out by age group, which keeps the course fairly uncrowded during each race. It has become more crowded over the years, and, like any race at the start, there is a crush of people. Things get better after you turn left and head along the beach and people find their proper place in the pack. We did notice this year that there seemed to be fewer spectators in past years.
Parking can be a challenge, so if your hotel has a shuttle option, I suggest going with that. Or, at least, carpool with others to minimize the congestion. I guess not a lot of hotel shuttles want to drop you off at 6am on a Sunday...
Getting beer at the end of the race is really nice, but is less attractive to me at this race because I usually need to start the long drive home after the race in order to get everyone back in time for school on Monday, but the free pizza from Pizza Port is nice for a quick lunch prior to getting on the road.
If you want to run a fast course with supportive fans and incredibly speedy competition, this is the place for you. Even the non-elite races have many, many freakishly fast people running in them. If you simply want to walk the course with friends, they have a "People's Walk" option that accounts for that, too. If you want to watch some truly crazy-fast people, stick around for the elite races in the afternoon and you may see another world record beaten. Who can run a 5K on the street in under 13 minutes? Yeah, someone did that here.
It is worth noting that, on the Saturday before, they have races for kids who can just barely walk (diaper dash, toddler trot), all the way up to 12 years old (Jr. Carlsbad). Younger kids can experience the thrills of racing here without worrying about being trampled by all the adults :) read more
