It's simultaneously one of the most Feel Good and Feel Bad moments of the Rio Olympics so far. American runner Abby D'Agostino was running in a qualifying heat of the women's 5,000 meters when her knee gave out, and she fell to the track, colliding into New Zealand's Nikki Hamblin. Rather than run away, D'Agostino sacrificed her time to help Hamblin up and make sure she's okay.

"Get up. We have to finish this," D'Agostino told Hamblin, reaching out her hand and helping her back up.
