It'll be a difficult pill to swallow for T.J.'s wife, Marilee, and Amy's husband, Andrew, as the couple reportedly forged a romance after spending hours training for the NYC half marathon last year and the full one months later too.
They last competed in November 2022, just weeks before their love affair was made public with photos of them packing on the PDA while on vacation.
