Marshall agreed and said that he watch all of his races and can't wait to meet him in person, if he slows down long enough. Marshall then imitates when driving a Formula One car then falls back into his firetruck. Ron then introduces the other racers: Riff Rockenbock, Lionel Lightspeed and Willy "Wide Wheels" Junior, including The Whoosh's dastardly rival, The Cheetah. As she arrived at the grid area she shows off the drifting in front of the PAW Patrol pups causing them to cough. And then back on the grid. Chase commented The Cheetah is fast but Marshall replied The Whoosh is faster and nicer. The Cheetah is then at the podium watching the trophy. Then her cousin, Mayor Humdinger arrived to admire her and commented about the trophy. She then took his cousin's phone and takes a selfie with her "First place face" and when The Cheetah wins the race she will bring glory to Foggy Bottom. Then the crowd roared as The Whoosh arrived and he said that he was late because he is just finished eating breakfast and reminds everyone that its a great day for racing and flossing. Marshall is happy to meet him in person but The Cheetah is jealous to see him. Then Ron introduces to the audience to the crew who keeps the racers running, the Adventure Bay 500 pit crew. Marshall then commented that whoever they are, they are lucky then a horn caught their attention revealing a new vehicle bearing the PAW Patrol colors and stops at the pit lane. The door opened revealing Ryder wearing new gear and Ryder said that the Adventure Bay pit crew is the pups and the pups howls with excitement and Ryder reveals to them that he built the vehicle, the Mobile pit stop which they can allow repairing vehicles on the track. Ryder then pushes the button on his wristwatch revealing the command port of the vehicle. The Cheetah commented that no one is touching her vehicle. The Whoosh heads for the pits and The Cheetah contacts her cousin to sabotage The Whoosh's vehicle by using super glue. Cat Rocky then uses his claw and glues The Whoosh's tires. And the two Humdingers said "If you can't beat 'em, cheat 'em." Ron commands the racers to head to the starting line their engines are revving. The crowd is cheering as Ron Rapidfire announces the start of the Adventure Bay 500 with ten laps around the track. With Mayor Goodway acts as an official starter/flagman of the race. Mayor Goodway said "Ready, Set, Race!" with Chickaletta spooked at the starting lights and the race cars zooms away from the starting line except for The Whoosh who is stuck at the grid. The Whoosh then calls the pit crew pups to rush to his aid but Marshall steps up and examines his vehicle and noticed the glue. Marshall then softens the glue using his water cannons allowing The Whoosh to catch up to the leading cars. The Whoosh thanks Marshall about the fix and compliments that Marshall has a heart of a racer. The Cheetah noticed The Whoosh is catching up and Mayor Humdinger reports to The Cheetah that Marshall undo their sticky scheme but The Cheetah assures that she has a lot of dirty tricks to play. She is first eliminating Lionel by removing his tires using a spike utilized on her vehicle while Willy, Riff and The Whoosh take the lead. Lionel looks down and lost that his race is over. But then Ryder and the Mobile pit stop zooms to them and gets them back to the race and Lionel is at the back of the pack. At another lap Riff amplified her speakers to take the lead but The Cheetah emits a smoke screen using her vehicle causing Riff and Willy to crash at the hay bales and the mud and Ron assumed that the smokescreen is a foggy weather condition. The Whoosh emerged from the crash unharmed followed by the Mobile pit stop. Chase then uses his winch to tow Willy's car out of the mud. After that Zuma commented that his car needs a wash. Marshall managed to take out the fire off Riff's engine intake and then the pit crew pups begins to pit the two racers. The Whoosh then have a neck to neck against The Cheetah, as Marshall begins to worry about what will happened to his racing idol.
Rocky comments that The Whoosh takes the lead now. But Marshall tells them that its too soon and The Whoosh is always going to take the box (going to the pits) and that way he has fresh tires and plenty of fuel to get to the final lap. The Whoosh then confirms to Marshall that he could box. At lap nine, The Whoosh heads to the pits and the PAW Patrol begins to repair his car and also Marshall and Rocky gives The Whoosh an energy bar to replenish up. And The Whoosh zooms from the pit lane to the race track. As he caught up Mayor Humdinger contact that The Whoosh is gaining up but The Cheetah have a plan to make him go slower. And using a device causing his vehicle to lost control and the racers takes advantage to overtake and The Whoosh stops at the grass area followed by the Mobile pit stop. The Whoosh said he felt a bang on his arm. Marshall then activated his X-ray screen and reveals The Whoosh had sprained due to that accident. He tried to drive but cannot. Chase commented if he doesn't he will lose the race but Marshall commented about the things that The Whoosh's race car have and The Whoosh points that Marshall should drive. Marshall is shocked to get that decision but with The Whoosh and the PAW Patrol's encouragement Marshall begins to take his helmet on and race. As The Cheetah takes the lead she commented that the race is easy even she drives backwards as she takes on the final lap. But she snapped and Ron noticed The Whoosh's car is gaining on The Cheetah but who drives it. Mayor Goodway commented that it was Marshall and the crowd goes wild. The Cheetah begins to drive serious and as Marshall takes the lead and heads for the final stretch The Cheetah activates her suction dart to slingshot to victory leads to Marshall and The Whoosh's car spins around until The Cheetah crosses the finish line winning the Adventure Bay 500 with Mayor Goodway saddened at the race, followed by Riff, Lionel and Willy to cross the finish line but not Marshall who is dizzy at the time. The PAW Patrol rushed to his aid and Marshall lost the race and his confidence but the pups complimented that he did a great job. The Cheetah is then celebrating her win at the podium along with her cousin. The Whoosh goes near Marshall but Marshall said sorry about he lost the race. The Whoosh assured that he will get better next time but Marshall said there will never be a next time since he will stop racing, which saddened the PAW Patrol. Ron announced that due to The Whoosh finishing last all of the racers are tied for 1st place. Mayor Goodway is delighted on the news. Ron announced that the tiebreaker race will settle at the Around the World Road Rally. The Cheetah asked Mayor Humdinger to keep her trophy and she aims for the Road Rally Trophy. Ron asked The Whoosh that if he return to race again. But The Whoosh said that as long as his arm broke he is not safe on the race course. Rubble said that he can't win the championship. Chase suggested Marshall. Marshall protested against this and said that he will never race and lose for The Whoosh again but The Whoosh suggests that if he trains Marshall. Marshall will improve and win the race Ryder then tells him that the Pups are here to back him up. Chase and Rocky then cheered Marshall to give it a go. Marshall agreed and Ron announced that Marshall is racing for team Whoosh and gives him good luck. Marshall said he is going to need it.

But he strayed too far causing Rubble, Rocky and the rest of the PAW Patrol to go after him. He crashed on a cone and his tire punctured. Marshall said that he can't race even on his firetruck. The Whoosh goes near him and tells him to smile and say that racing is fun. Rocky managed to fix Marshall's tire and he returns to free practice.

But when The Whoosh trained him it would be impossible for the Humdingers to cheat. The Cheetah suggest that she needs to upgrade her car by taking the parts from the other racers. Mayor Humdinger liked the plan and The Cheetah tells him to prepare the blimp and go car shopping.
