Age: 27. Club: Star of the Sea AC. Coach: Feidhlim Kelly. SB: 3.30.42 NR. PB: 3.30.42 NR

Ray Flynn’s 1,500m record had stood since 1982, and Coscoran has already run inside it four times now, a real final prospect if he can keep his head in the game.

Luke McCann (1,500m)

Age: 25. Club: UCD AC. Coaches: Thomas Dreibigacker and Clark McCann. SB: 3.34.76. PB: 3.34.76
