The 2012-2013 and 2013-2014 editions of the USA Swimming Grand Prix Series had just 6 stops, with a bit of a gap in March.
The 2014-2015 and 2015-2016 seasons, however, are at least considering the addition of a 7th date in March, and in 2015 extending the series into July.
The updated quad plan, which is still a very loose framework and subject to change, includes a place-holder for a “TBD” March stop on the series that is now flush with cash after signing on individual race prizes from new sponsor Arena.
There’s not a whole lot of new information on this schedule yet, as dates and host sites are still being worked out, but it also includes a potential December Duel in the Pool meet for 2015, which would be the first since 2011.
