They won the Penn Relays HSB DMR Championship of America last year:
1 La Salle Academy (Providence, RI) 10:12.10 Matthew Bouthillette (3:09.44), Cameron Morenzi (50.96), Daniel Paiva (1:57.20), Jack Salisbury (4:14.52)
It came down to Salisbury's kick as he passed the other teams in the final 100m to clinch the win.

They are also the defending national 4x1mile champs for indoors:
"The boys’ “Long Rangers’’ of La Salle – dominant all season – entered the Nationals on Saturday with a real shot at toppling the United States 4-mile relay indoor record of 17:07.17, set last year by a foursome from Christian Brothers Academy. Although the Rams fell shy of that goal, the combination of Dan Paiva, Matt Bouthillette, DJ Principe and anchor Jack Salisbury were nonetheless impressive. They posted a winning time of 17:11.07, eclipsing the state and New England record of 17:20.20 set in 2010 by a Chariho High relay. (The Chargers’ performance was a national standard before elimination by the Christian Brothers’ team.) Coming in behind the Rams on Saturday was the Davis TC of Utah in 17:11.44.:"

Meanwhile, the LaSalle girls won the girls 4x1mile at Outdoor Nationals last June, so their girl's team is very good too:
"The Rams carry a United States title back to their Smith Hill-area school. They aced the New Balance championship in the girls’ 4×1-mile relay, clocking a state and New England-record 20 minutes, 14.01 seconds for the victory. The foursome of junior’s Karina Tavares and Eliza Rego, freshman Emily Kane and senior Sheridan Wilbur did the honors for La Salle. Their performance not only betters the 2013 R.I. mark of 20:46.96, set by Barrington, but the New England record of 20:23.20, clocked six years ago by a relay from Newton South High in Massachusetts."
