 On 26 June 2016, a month before the start of the 2016 Summer Olympics, the Rio Olympic Organizing Committee finally took possession of the velodrome, marking the end of construction.The very first training events held at the venue took place the previous day.The venue's opening was not without controversy, however, when state prosecutors inquired about the selection of Engetécnica and subcontractor company Zadar for construction and operation contracts, without a proper bidding process.
