In 2022, Tomac won a record-setting sixth Daytona Supercross, surpassing previous record holder Ricky Carmichael with five.

In 2009 Tomac won the 125cc FIM Junior World Championship, held in Taupō, New Zealand.Eli Tomac became the first rider to win their professional debut in 2010, securing victory at the 250cc AMA Motocross season opener at Hangtown in Rancho Cordova, California, while riding for Team Geico Honda.

During the 2013 Supercross season, Tomac narrowly missed defending his title, finishing two points behind Ken Roczen despite securing five wins.

After six rounds of the 2017 Monster Energy AMA Supercross season, Eli was in fourth place in the 450 class overall point standings.

At round 15 in Salt Lake City, Utah, Tomac put forth a dominating effort to win his 9th supercross main event in 2017.

[12] Going into the penultimate round of Supercross in East Rutherford, New Jersey, Tomac held a 3-point lead over Dungey.

At the final round of Monster Energy AMA Supercross in Las Vegas, Nevada, Tomac finished 2nd and Dungey placed 4th.

Coming into the tenth round at Daytona, Eli found himself tied on points alongside Ken Roczen with 200.

He battled Chase Sexton until the final round where he held a 1-point lead going into the first moto at Fox Raceway II in Pala, California.

Fresh off from winning both the 2022 Supercross and Motocross championships as well as the MXON with Team USA, Eli was a strong favorite for a repeat of the previous year.

For a majority of the 2023 AMA Supercross season, the championship would be a tight three-way battle between Eli, Cooper Webb, and Chase Sexton.

After Webb dropped out of the supercross season due to injury at round 15, the championship would once again come down to Eli and Sexton.

However, while leading the main event Eli overshot a jump that led to a hard landing in which he managed to stay on his bike.

The force of the landing ruptured his Achilles tendon, dropping Eli out of the race and ultimately ceding the championship to Sexton.

Eli re-upped with Star Yamaha for the 2024 SuperMotocross Championship, signing to compete for the entire season.

In the second half of the supercross season, Eli began to show pace and consistency, with several podium finishes and a win at round 12 in St. Louis, Missouri.

The race as in 2018 was also held at Red Bud MX and started out with a déjà vu feel as it had rained heavily the night before leaving the track soaked and muddy.

Chase Sexton finished 2nd in Moto 2, with Cooper scoring a 4th place leaving Team USA in the driver's seat for the overall win.

In Moto 3 Eli started 10th, but advised through his pit boards that Chase was in 3rd and it wasn't needed for him to race with urgency as they had enough points to win.

Tomac holeshotted the second moto closely followed by Switzerland's Jeremy Seewer, Slovenia's Tim Gajser, and Jorge Prado.
