2026 Philadelphia Supercross – 450SX Heat 1 | Round 15

The 450SX class opens its night at Round 15 of the 2026 Monster Energy AMA Supercross Championship — and Heat 1 at Lincoln Financial Field in Philadelphia, Pennsylvania marks the beginning of a premier class evening that carries massive championship implications heading into the final rounds of the season.

Philadelphia is a venue that has delivered memorable Supercross nights, and Round 15 returns to Lincoln Financial Field as an evening show for the first time at this stadium. The outdoor atmosphere under the lights adds a unique dimension to the 450SX heat races, and in a championship as tight as the 2026 title fight, the intensity on the gate from the very first race of the night is at an absolute peak.

Heat 1 is where the tone is set for the entire evening. A strong result means a prime gate pick for the main event — and at a venue and in a championship where starting position can be absolutely decisive, no rider in the 450SX field is willing to leave anything on the table in the opening heat race of the night.

With the 2026 450SX championship entering its final stretch and the standings tighter than ever, every race from here on out carries the potential to reshape the title fight. Philadelphia Heat 1 is the first piece of a night that nobody in the premier class can afford to get wrong.
