It's one of the largest single events in the valley.
The Lewiston Supercross draws thousands of spectators every year while taking motor sports enthusiasts for a wild ride.
But before fans cheer for their favorite rider, before the race begins, and even before engines start to rev, crews are busy smoothing the jumps, fixing the straight away and getting the tracks in top shape for the big event.
Since it first started 6 years ago, creator Eric Christiansen has seen the event grow bigger and better. But this year, he says the weather almost put a damper on it.
"A week ago we didn't think we were gonna have the race because the arena was so wet and we got it all dried out, got it drained off, got the tracks built," said Christiansen. "We had practice last night for couple of hours before the rain hit, the tracks are actually in great shape right now."
Crews are still making last minute preparations and by Saturday, more than 200 participants, locally and from the northwest, will ride down the tracks.
Riders Swade Malloy and Tyler Carson are both from Orofino. They've been racing for several years and say it's one of the greatest sports they've been involved with.
"Just be out there with other kids your age and just trying to win," said Malloy.
"It's an adrenaline rush, it really gets your heart pumping and it's the biggest adrenaline rush I've ever had so it's the a lot of fun," said Carson.
Because fun is what Eric Christiansen could only hope for when the gates open on Saturday.
"Just a good event, safe event, riders not getting injured, putting on a good show for the crowd," said Christiansen. "It's fun to watch it all come together."
Gates open at 4:30 and the race starts at 6:15. The event is expected to draw more than 4,000 people.
