FIG PRESS RELEASE
… published by the FIG Executive Committee at the close of its ordinary meeting, May 07- 08, 2014, in Kuwait City (KUW) …
* The second Olympic qualification will be held at the Test Events in Rio de Janeiro (BRA), from April 16 – 24, 2016.
Recall that the London Test Events were in early January 2012. Bad timing, so close to Christmas and New Years, for many of the athletes.
April is better. Overall. But finding out so late whether or not your nation qualified for the Olympics is going to be even more stressful than it was in 2012.
