Three-quarters of Belgium's men's 4×400 relay team at the Rio Olympics is made up of brothers from one family.
Leg 1 of Belgium's team, which qualified for Saturday night's final, was run by Julien Watrin. After that, the Borlee Brothers took over, with Jonathan followed by Dylan and then Kevin running the anchor leg. Kevin and Jonathan, both 28, are twins. Dylan, 23, is the baby.

The men's final Saturday night is the last Olympics track and field event in Rio.
The athletic bloodlines extend to their sister, Olivia, who qualified from the Olympics in the women's 200 meters.
The brothers are not shy of posting shirtless shots on their Instagram pages (Kevin, Dylan, Jonathan).
