450 Supercross race start


The stadiums of Monster Energy Supercross are designed to amplify noise. Fill that setting with the thunderous roar of dirt bikes and tens of thousands of cheering fans, and you’ve created a sound experience unlike any other. There’s something else to listen to, though. The voices of Monster Energy Supercross will make you a smarter, more informed fan.

Leigh Diffey

Leigh Diffey has called nearly every sport imaginable, but supercross is close to his heart. He broke into broadcasting in his native Australia calling motocross and supercross events, and then climbed the ranks in all manner of motorsports, now serving as play-by-play commentator and host for NBC Sports. One of the most prolific voices in racing, he’s covered Formula 1, NASCAR, IndyCar, IMSA WeatherTech Sportscar Championship, MotoGP and more. In addition, he is NBC Olympics’ primary announcer for Track & Field and has called numerous events at both the Summer and Winter Games. Whether it’s racing, track & field, bobsled, skeleton, luge, rugby, or more, if you’re watching, it’s likely Leigh’s voice calling the action.

Ricky Carmichael

Few sports get to put their GOAT (Greatest of All Time) into the TV booth, so fans of Monster Energy Supercross are fortunate to hear the analysis of the legendary Ricky Carmichael each weekend. Carmichael has won more dirt bike races than anyone, so his insight is worth hearing. While known for a fanatical work ethic as a racer, Carmichael’s analysis often focuses on the mental side. Few knew how to plan a racing strategy like Carmichael, and now he gets to drop that insight into the broadcasts, as well as his weekly Title24 podcast alongside fellow Hall of Famer Ryan Villopoto.

Will Christien

Will Christien is an action-sports enthusiast through and through. She got her start in wakeboarding, first as a competitor and later doing dock-side interviews with the other athletes for NBC Sports (while also still competing!). She’s no stranger to motorsports, either, having worked with Global Rallycross Championship racing and both Pro Motocross and Monster Energy Supercross in the past. Christien is a passionate fan of the action, and can bench race with the best of them. You’ll hear that come through with her reporting and podium interviews throughout the season.

James Stewart

Known as the FMOP (Fastest Man On the Planet) in his racing days, James “Bubba” Stewart took riding skill to a new level when he broke into the pro ranks in the early 2000s. He became one of this sport’s most recognizable names, and it all stemmed from his relentless dedication to the craft. Famously, as a kid James would fall asleep watching an endless loop of races on VHS! Retired since 2016, Stewart now lends all that knowledge to the Monster Energy Supercross TV broadcasts as an analyst, and also dives deep with his weekly Bubba’s World podcast.

Jason Thomas

Jason Thomas spent nearly two decades grinding out the privateer life in Monster Energy Supercross and sits in the top ten in all-time starts in the sport. After retiring in 2013, he has climbed the ladder as an insider and analyst, joining the Pro Motocross Championship broadcasts as a reporter in 2022, and now attending all 31 SuperMotocross World Championship rounds as part of the Peacock and NBC Sports team. Thomas earned his keep in the sport through hard work and constant analysis of how to get better, fitter, and faster, and now he can train that keen eye on today’s racers and ask the insider questions from the podium.

Jason Weigandt

A veteran broadcaster and journalist within the sport, Jason Weigandt broke into the business out of college, reporting for Racer X magazine. His real penchant was for public speaking because, as he saw it, something most people claim is their worst fear probably wouldn’t have a lot of competition. He eventually took the microphone and transitioned into play-by-play for NBC Sports while continuing his Racer X work. Weigandt has called Grand National Cross Country, American Flat Track, Arenacross, MotoAmerica, EnduroCross, ATV Motocross, NASCAR, and off-road truck racing. This year he returns to the Monster Energy Supercross broadcast team, which he first joined as part of the Supercross Live audio webcast in 2005.

Steven “Lurch” Scott

The announcer affectionately known as “Lurch” has brought his outsized personality to NBC, CBS, the Outdoor Channel, Speed, OLN, and Fox Sports over the last 25 years. He’s traveled the world covering FMX, Monster Jam, and Major League Fishing in addition to SuperMotocross, which is his true love. Lurch watched his first supercross race in Atlanta at the age of 18 and then became a racer, mechanic, and FMX judge. Mind you, he wasn’t entirely qualified for all of those jobs, but he wasn’t afraid to try! As for his role now, as hype-man from the floor and reporter for Race Day Live, there is no question about his credentials. No one gets a crowd going like Lurch!

Dan Hubbard

Dan Hubbard grew up in Southern California riding BMX bikes, skateboards, surfboards, and motorcycles. His passion for action sports led to a partnership with Monster Energy in 2006, and he has been producing live events for them ever since. After announcing at the Monster Energy Cup in 2016, Dan joined the live hosting supercross team, where he hosts Race Day Live during the day and calls the action for the live audience at night. Hubbard’s tireless enthusiasm for the sport makes him the perfect voice to keep fans on top of the action, and he never stops researching and working to bring even better stories to the fans.

Katie Osborne

Indianapolis native Katie Osborne has been a motorsports and automotive enthusiast from a young age. Graduating with a Sports Communication – Broadcast degree from Indiana University, she landed her first job at the Indianapolis Motor Speedway, and her career has been filled with racing ever since. Katie has covered Formula 1 for Amazon, Mecum Car Auctions for MotorTrend, and Rallycross on NBC and Peacock, and is now part of the burgeoning F1 Explains podcast. She’s also been a sideline reporter for the NFL, NHL, and the MLB for FOX Sports, and began adding her reporting experience to Race Day Live broadcasts last season. This year she will co-host pre-and-post race shows with Jason Weigandt at select rounds.

Haley Shanley

An avid motorcycle rider and powersports enthusiast, Haley Shanley has served as a TV host, producer, and trackside reporter over the past decade, covering short-course off-road racing, Snocross, Snow Bike, Ice Oval Snowmobile, Pro Watercross, regional Supercross, and Sprint Car racing. While closely woven into the broadcast team for Championship Off-Road and Amsoil Championship Snocross, Shanley has always wanted to join the world of Monster Energy Supercross, which she did last year by joining the Race Day Live team and also handling podium interviews during the live show. Her ability to get info from the racers adds a lot of texture to each race weekend, so be sure to listen when Haley jumps in with a scoop.

Justin Brayton

One of the most well-respected racers in recent memory, Justin Brayton came from off the industry radar in Iowa to become one of the most reliable talents in Monster Energy Supercross. His long journey culminated with a legendary win at the Daytona Supercross in 2018, as well as five-straight Australian Supercross Championships, and six King of Geneva titles in Switzerland. A thinking man’s racer, Brayton has a feel for details many miss and has a great relationship with today’s racers, who often lean on him for advice. While he’s probably still fast enough to battle for top five in a main event, he’ll instead provide expert commentary alongside Dan Hubbard in the Race Day Live booth this year.
