USA Swimming announced Tuesday that the 2018 U.S. Open Water Nationals will take place in Tempe Town Lake, Tempe, Arizona, scheduled for May 4-6.
This is a major change after the championships have recently been at either Castaic Lake in California or Miromar Lakes in Florida. Tempe Town Lake is actually a reservoir on the dry bed of Salt River. Like both Castaic and Miromar, it is man-made.
Three distances will be contested, with the 10k National Championship on Friday, the Junior National 5k on Saturday, and the National 5k and Junior 7.5k on Sunday. Spots on the 2018 Pan Pac and Junior World Championship rosters will be up for grabs, as well as positions on the 2018-19 Open Water National and Junior National teams.
“Tempe Town Lake has hosted a number of events, and our athletes and coaches will enjoy a tremendous venue for the 2018 USA Swimming Open Water National Championships,” said Bryce Elser, USA Swimming National Team Open Water Program Director. “We are excited to extend the Junior National Championships format in 2018, which will not only provide a great competitive opportunity, but will serve as the qualification for FINA Open Water World Juniors.”
After the addition of the Junior 5k in 2017, the 7.5k will be contested in 2018 and 2020 to mirror the event program at the Open Water Junior World Championships.
For an idea of the water temperature, Tempe Town Lake was recorded at 73 degrees Fahrenheit in May of 2015. It is also the host of the swim at Ironman Arizona, so the venue has experience hosting a large scale event.
