The Bull Run 5K is a chip timed accurate 5k run/walk. The Calf Mile is FREE for kids 10yrs and under. All proceeds go to ALS of Michigan to help our pALS (people with ALS) here in Michigan. There is a lot of symbolism in The Bull Run. First the name, my dad, Kenneth C. VanBlaricum passed from ALS in Feb. 2010 and early in his life he worked in excavating, his nickname was Bull . The Bull Run is named in honor of my father. Second, the finishers medal is a dog tag honoring the time he served in the National Guard out of the Howell Armory and was called into active duty during the 1967 riots in Detroit. The start/finish line is on the ball diamond. You will run by first base, which is the position played by Lou Gehrig, and as you finish the race you cross home plate scoring a home run for our pALS(people with ALS) here in Michigan. This run continues to be a dream come true to honor my father. Thank you for being a part of it. www.thebullrun.org
