Rob Heffernan has qualified for a fifth consecutive Olympic Games following a fourth-place finish in the 50km event at the IAAF Race Waking Challenge meeting in Slovakia.
The Corkman clocked a time of 3:48:44. Brendan Boyce, who finished fifth in a time of 3:48.55, also secured the qualification mark for the Rio Games.
Both walkers also met the standard for this summer's World Championship in Beijing.
