Eli Tomac probably goes into this years San Diego supercross with a load of confidence. The two-time AMA supercross champion and five-time AMA motocross champion is the most successful rider in the field this weekend, when it comes to San Diego.

Tomac has four wins in San Diego, two in the 250 class and two in the 450 class, those wins coming in 2011, 2013, 2019 and 2024. Cooper Webb has won on three occasions, twice in the 250 class and once in the 450 class.

The first 450SX Class race held in San Diego was on October 25, 1980, and is one of just two October Supercross races in the history of the sport (1984, Oakland). Mike Bell had clinched the title over a month before in Philadelphia and tacked on the seventh win of his title season in the San Diego finale.

The San Diego Supercross was held in Jack Murphy/Qualcomm Stadium 31 times from 1980-2014 and has since been demolished. From 2015-2024 the series moved to PETCO Park where there were eight races held. 2025 marks the 42nd San Diego Supercross and brings in a new venue, Snapdragon Stadium. Brand new Snapdragon Stadium, home of the San Diego State Aztecs, was built near the site of former Supercross mainstay Jack Murphy/Qualcomm Stadium and opened in 2022.

The first ever 250SX Class race held in San Diego was on January 26, 1985, in Jack Murphy Stadium and Todd Campbell’s #415 Kawasaki took the checkers as the classes first winner. Campbell switched to a KTM by season’s end and finished fourth in the inaugural Western Regional 250SX Class series’ point standings behind Bobby Moore, Mike Healy, and Billy Frank.

San Diego has hosted a 250SX Class race in every 250SX Class season except for 1988, 1997, and 2021. 2025 will be the 39th time the gate will drop for a 250SX Class race in San Diego and first in Snapdragon Stadium. Snapdragon Stadium is the 56th different venue to host a 250SX Class race.
