The Carlsbad 5000, is a popular 5k and 20k (more on that in a bit) run that happens annually in Carlsbad, California. The event, which is put on by the same group that hosts the nation wide Rock 'n' Roll series of races features a very fast and flat 5k road course.
Participants looking for something a bit longer can opt to run the "all day 20k" which is actually four separate 5k races back to back to back to back.
The 5k runs on Sunday, but there is plenty of action Saturday - for the kids! There's a huge slate of kid's single age races over distances ranging from the quarter mile up to the mile, depending on age.
This is a popular event that regularly attracts thousands of runners each year!
The Carlsbad 5000 5k course is a fast oceanfront course with a slight uphill section and long running gradual downhill.
