The course is open for 3 hours for the Half Marathon & 1 hour for the 5k. If you surpass the limit, you’ll but there are some runners that need a bit more time. If you finish after the above time limit, you’ll still get a medal, but you’ll need to move to the sidewalk (the course is controlled by the CHP and police only for the three and a half hours). Runners are welcome to start early but note they will not have an official time.
