I did the 10K. This race has lots of runners and only 3 waves. I was in wave 3 and pretty much fast walked the first mile because there were so many people. They should probably have more waves so it could be spaced out a little more especially for the start of the race. The race also had a portion where you were running the San Gabriel bike path which is pretty narrow. Since there were a lot of runners, it’s difficult to pass other people because you didn’t want to fall into the ditch. Post race was great because lots of food and vendor freebies. I liked this race. I might do this race again.
