An elite triathlon race in Mexico ended dramatically Sunday with one brother helping another across the finish line.

At the final race of the World Triathlon Series in Cozumel, Mexico, Jonny Brownlee of Britain was leading with less than half a mile to go when he slowed and staggered over to a water station. His brother, Alistair, in a battle for second with Henri Schoeman of South Africa, veered over, pulled Jonny’s arm over his shoulder and began hauling him along. Meanwhile, Schoeman raced on for the win.

When the Brownlees reached the finish, Alistair pushed Jonny across the line in second. Jonny immediately collapsed. He was admitted to a hospital, suffering from dehydration.
