Where: Nassau, Bahamas
When: May 02 - 03, 2015
More: This is really a thing now...a dedicated event for relays only. After last year's inaugural success, this should further attention to relays and increase competitive times and focus, especially with Olympic qualifying times on the line.
Fun Fact: So, when can we see the 4x200, 4x800, and the medley make it into the Games or at least the Worlds?
