Leila, Liina, and Lily Luik are not expected to medal when they compete at the 2016 Olympics in Rio.
But the three Estonian marathon runners will make history, as the first set of triplets to compete together.
The triplets, now 30, will race in their first Olympics this summer, despite only seriously training for marathon running since they were 24 years old.
Reuters recently followed the triplets as they trained for the biggest race of their lives.

They’re believed to be the first triplets to ever compete together in the Olympics.
The triplets are from Tartu, Estonia’s second largest city known for its university. Tartu is about 100 miles from Estonia’s capital, Tallinn.
