Career
Caknakis trains under the tutelage of 1988 Olympic marksman Ján Kermiet for the national running target team, while shooting in his native Krnov. Caknakis was among the youngest athletes (aged 17) to be selected for the Czechoslovakian team at the 2004 Summer Olympics in Athens, competing in the men"s 10 m running target. He managed to get a minimum qualifying standard of 580 to join with fellow marksman and 1996 Olympic bronze medalist Miroslav Januš and gain an Olympic berth for the Czechoslovakian Republic, following a top five finish on his senior debut at the ISSF World Cup meet a year earlier in Munich, Germany.
He scored a modest 276 in the fast-moving round, but could not improve much better at the very end of the qualifying stage, falling to a distant seventeenth in a 19-shooter field with a total score of 560 points, just eighteen points adrift of the Olympic final cutoff.
