Dallas has no shortage of organized running events. But all 5Ks are not created equal. The inaugural Disco Run on May 19 features a DJ-manned refreshment stations, a tie-dyed T-shirt and an oversized disco finishers medallion. And of course, there's a killer after party. As if that wasn't enough to get you off your couch, the race benefits Nobody's Normal, a nonprofit dedicated to mental health awareness.
