Dirt Wurx spread the best soil the circuit has onto the floor of the Edward Jones Dome and Monster Energy Supercross has gone to work on a very fast, flowing track. Practice has concluded, where Dean Wilson and James Stewart finished at the top of their classes in timed qualifying. Wilson’s long legs have helped him excel in the massive whoop section, while Stewart charged the bowl turns with precision.

Stewart’s day was not without incident, as he took a spill in the final session of the day. It would end up being a non-factor, as he had already posted an unbeatable lap.
