The Down Syndrome Network of Greater Greensboro invites you to participate in its first annual 5K walk/run, in honor of World Down Syndrome Day! People with Down syndrome have an extra chromosome, so this race has something EXTRA too – Official times will be recorded at the 5K finish line, then runners will go on to DASH the extra 0.11 miles to finish at 3.21 miles, in honor of the 3rd copy of the 21st chromosome present in people with Down syndrome. And if you’re lucky, you may be accompanied through the second finish by a dasher with Down syndrome!
