Did Johnny Manziel’s wife cheat at a half-marathon? Allegations of improper behavior are being raised after Bre Tiesi-Manziel, a fitness Instagrammer, finished the Divas half-marathon in Temecula, California, with record-breaking splits. Overall, Tiesi-Manziel completed the 13.1-mile race in 1:58:22, course records show. That’s an average 9:06 per mile pace overall, better than the average woman, but not earth-shattering. A closer look at Tiesi-Manziel’s splits are raising questions. #InsideEdition
