USA go high-tech to tackle Tokyo challenges

There has been plenty of turmoil in the US Olympic movement since the 2016 Rio Games.

US Olympic officials are counting on cutting edge technology to help American athletes refine their training and prepare for the unique challenges of Tokyo in pursuit of another dominant display at the 2020 Games.

Wednesday marks the start of the one-year-to-go countdown to Tokyo 2020, and Finbarr Kirwan, the vice president of summer sport performance for the US Olympic and Paralympic Committee (USOPC), said the milestone was a good opportunity to assess preparations for the Games.
