Riddle statement

Four runners—Ana, Beto, Cora and Diego—came in positions from 1 to 4, without ties.

It is known that exactly one of these statements is false:

  • Ana: “I wasn't the first.”
  • Beto: “Ana came second.”
  • Cora: “Diego arrived immediately before me.”
  • Diego: “Beto came second.”

In what order did they arrive?
