Retired NFL defensive end Isaac Rochell admits that training for a marathon is "way harder than football" as he prepares to run the Chicago Marathon with a target finish time of 3:15.
"I went from wearing this jersey [NFL shirt] to this jersey [marathon bib]."
Rochell, 29, spent seven years in the NFL playing for the Chargers, Colts, Browns, and Raiders before announcing his retirement on his wife's podcast, saying he's "super happy to be done" and "really accomplished". He has now found a new challenge in marathon running.
