On Oct. 12, 2019, with a time of 1:59:40, Eliud Kipchoge of Kenya became the first person to complete a marathon in under two hours. He wore a custom, upgraded pair of Nike Vaporfly 4% shoes, proven by CU Boulder research to reduce the metabolic cost of running by 4 percent.
Prior to his historic race in Vienna, a mathematical CU study led by integrative physiology professor Rodger Kram determined the course exhibited near perfect conditions for Kipchoge to succeed.
“I love math with a purpose,” study co-author and former CU fellow Kristine Snyder told CU Boulder Today.
