This is our second year of doing the Riverside Color Vibe 5K run. You sign up ahead of time for the upcoming event. In the case of the Riverside event, it happens on November 11, 2015. Next year it will probably be around the same date. When you sign up you can choose to purchase t-shirts, socks, and other clothing. Then you purchase color packs. This is where the fun begins. The whole idea of this run is to spread this color all over yourself and other friends while on a 5K run. By the time your a finished, you are covered in all kinds of color. The run is short. It is at a regional park and you are always kept close to the center of the activities during the run. Before the run starts, they have a stage set up with music playing and dancers. It kind of gets you into the mood of doing the run. This year lots of people were gathered around the stage. Color was flying everywhere. The color packets are non-toxic. They are made of corn starch with coloring added. During the run you pass by about 5 different color stations where people are throwing around the color. Each station is a different color. There was also a water station to get some refreshment. At the end of the run they have water bottles and other drinks to refresh. Because of the colors, make sure to place your cell phones in zip lock bags. Otherwise they will get color dust in all of their ports. Also bring towels for the car ride home. Unless you want colors in you car. It gets everywhere. This time someone threw color in my ear. It eventually came out. Once I got home, I took a shower and could see colored water going down the drain. It was a lot of fun and we will be going next year.
