T.J. Holmes suffered a medical emergency during the Chicago Marathon, leading to his hospitalization after experiencing an IT band injury exacerbated by a collision with another runner. Accompanied by his partner, Amy Robach, Holmes faced several issues on race day, including missing pre-race nutrition and hydration, before withdrawing around mile 21. Initially reported as an Achilles injury, the condition was later clarified to involve the IT band. Despite the setback, Holmes intends to participate in the New York City Marathon in November. The couple, formerly co-hosts on ABC's 'GMA3', have been living together since their romantic relationship became public, following their respective divorces.
