The Nelson Recreation Center serves as a multi-purpose facility, primarily used for indoor tennis and intramurals. Renovations were completed in January of 2002 on the former Duke Nelson Arena.
A new surface was installed with lines for several tennis, badminton and volleyball courts. The north end of the facility now has a state-of-the-art golf area, complete with a hitting net, video camera and computer for swing analysis as well as pickle ball courts. The south end of the facility now is home to Middlebury's new climbing wall. Increased lighting and three new offices were also part of the renovation.
The Duke Nelson Arena was home to Middlebury's men's and women's varsity ice hockey for 50 years. The arena hosted the 1995 and 1997 NCAA Division III National Championships, as well as the 1996, 1997 and 1998 ECAC Alliance Championships. The arena was enlarged and renovated in 1983 and contained one of the largest ice surfaces in the division. At 200 x 90 feet, the skating surface is just five feet short of Olympic dimensions. The rink accommodated up to 1,800 spectators.
