[3] The February 2009 test event held at the Olympic venue was won by the American duo of Shauna Rohbock and Elana Meyers.

[12] American bobsledder Shona Rohbock expressed concerns on the 19th that the track could generate speeds that are too dangerous for racing.

[13] Elana Meyers, an American brakewoman, commented on Twitter that same day that "We (referring to her and her driver Erin Pac) went 145 km/h (90 mph).. that's fast!

[13] Minor changes were made to the track on 22 February 2010 after bobsleigh four-man teams from Latvia and Croatia rolled over in supplementary training.

[14] Following a meeting with 11 team captains, training runs were postponed by the FIBT until later that day to adjust the shape of turn 11 so it would be easier for sleds to get through the rest of the track without crashing.

Meanwhile, defending world champion Minichiello's sled flipped over after turn 12 during the third run, but the British driver and her brakeman Cooke walked away from the crash at the finish line.

Test event winners Rohbock and Meyers of the United States, the defending world championship silver medalists, finished sixth and third, respectively.
