They also won the FIVB Beach Volleyball World Championships in 2003, 2005 and 2007. The pair set various records throughout their partnership, including a win streak of 112 consecutive matches (19 consecutive tournament titles) in 2007–2008, breaking their own previous record of 89 consecutive match wins. They have been called "the greatest beach volleyball team of all time."

Walsh was born in Santa Clara, California, the daughter of Margery Lee (née Formico, Italian American) and Timothy Joseph Walsh. Walsh grew up in Scotts Valley, six miles (9.7 km) north of Santa Cruz. She attended grade school there until the end of her middle school years. Before she started high school, her family moved to San Jose. Walsh attended Archbishop Mitty High School, competing on the volleyball and basketball teams. She led her school's teams to three state championships in volleyball, in 1993, 1994 and 1995. She also led her school's basketball team to a state championship in 1995. She was named Gatorade National High School Volleyball Player of the Year in 1996, the first time the award was given. Walsh was also the #1 volleyball athlete recruit in the nation her senior year (1995.) While in high school she competed against her future beach doubles partner, Misty May-Treanor .

Walsh attended Stanford University on a volleyball scholarship. While there she was selected as a first-team All-American four years in a row, becoming only the second player in the history of collegiate volleyball to be chosen first team all four years of their collegiate careers. While at Stanford her school's volleyball team won over 90% of its matches, posting a 122–11 overall record. The Cardinal won four Pac-10 titles and three times reached the NCAA Final Four, winning the title in 1996 and 1997, and falling to Penn State in the championship game in her senior year in 1999. She was selected as the MVP of the Final Four in 1996, and was co-National Player of the Year in 1999. She was also the first player in PAC-10 history to record over 1,500 kills (1,553), 1,200 digs (1,285) and 500 blocks (502). Walsh is considered to be one of the best all-around players in collegiate volleyball history. She graduated from Stanford in 2001 with a B.A. in American studies.

Walsh Jennings plays professional beach volleyball on the U.S. AVP Tour and internationally on the FIVB World Tour. For most of her career she played with partner Misty May-Treanor, forming the most successful beach pairings in AVP history. May and Walsh formed a partnership on the beach circuit in 2001, finishing the season with the number five ranking in the world. In 2002 the team reached the number one ranking. They continued their dominance in 2003, winning all eight tournaments they entered and a then-record 90 straight matches, including the world championships where they upset defending world champions Brazil in the final.

In 2010 May-Treanor and Walsh extended a winning streak to 112 matches before losing to Olympic teammates Elaine Youngs and Nicole Branagh in the AVP Crocs Cup Shootout in Ohio. To that point the pair had won 19 straight titles.

She went on to break the career record for most wins by a female professional volleyball player when she won the FIVB Grand Slam in Xiamen, China. The win gave Walsh the 113th title of her career, breaking the old mark set by May-Treanor. Walsh and Ross won 21–14, 17–21, 15–12 over the Brazilian pair of Taiana Lima and Talita Da Rocha Antunes.
