Bryan Morseman is a competitive marathoner who uses Corduzin as part of his daily regimen. He placed 25th overall in the New York City Marathon in 2008. After running the Wineglass Marathon in the fall of 2008, he shaved four minutes off his time at the Pocono Marathon in the spring of 2009.

More recently, Bryan won the 2011 Wineglass Marathon. He has won four of the ten marathons he has participated in, and continued to use Corduzin as he prepared for the U.S. Olympic Marathon Trials in January 2012.

In May 2013 Bryan set a new record for fastest marathon on Delaware soil in 2:24:48 at the Delaware Marathon, besting the old record by 23 seconds which was set in 2011.

"I have been injury free, and have not had to worry about feeling tired, nor fatigued when I use Corduzin. The product is the real deal, and it can be used by anyone who is serious about long distance running. With hard work and Corduzin, I've lowered my half-marathon PR to 1:07 and my marathon PR to 2:20:11!"
