With two wins behind him this season, Wienen will be looking to add another overall win to his resume and extend his points lead. The four-time champion is on a mission to make it five-in-a-row and has shown no signs of slowing down thus far. Throughout the first three rounds there has been a noticeable difference in his training regimen that has produced better starts and allowed Wienen to jump out to the early lead. Wienen moves into Indiana with the hope to take home the coveted win.

However, just two weeks ago Hetrick was able to snag his first win of the season at the Muddy Creek National. The Pennsylvania native is still on the road to recovery from a knee injury he suffered as a result of a crash at the opening round, but it seems as if he is getting more comfortable as the weeks go by, ultimately producing results needed to take home his first AMA Pro National Championship. Hetrick holds the third place position in points heading into the fourth round, but will look to take the overall win as he continues his quest for the National Championship.

“I haven’t been able to run yet,” said Hetrick. “I’ve barely been able to jog, but I think if I can get to running again my knee will finally be better. I was able to win one moto at Ironman last year and hopefully we can put everything together to take the overall win this year.”

Perhaps one of the most consistent riders this season has been Maxxis/FLY Racing/Baldwin Motorsports-backed John Natalie. Natalie heads into this weekend after a podium finish at Muddy Creek and sits second in points. With this being only the second year that the ATVMX has competed at Ironman Raceway, the majority of the AMA Pro field will be placed on an equal playing field, but Natalie’s veteran experience will come into play as he strives to take home the win this Saturday.

“There’s a lot of times I’m not the fastest guy out there, but somehow I find a way to make it on the podium from my experience,” said Natalie. “It’s hard for people to understand but we are still tuning the bike and getting it dialed in. I just have to put the speed and consistency together to get a win.”

Maxxis/Root River Racing/JB Racing’s Thomas Brown will also be contending for the overall win this weekend aboard his Yamaha machine. Brown took the inaugural win here last year and will look to use that momentum to repeat his success this weekend. Brown took a hard hit during the second moto at the last round, but was able to rebound for a fourth overall. The Texas native will line up against twenty other racers all with the same goal in mind, to take home the win.

JB Racing/Root River Racing/Gold Speed Tires’ Jeffrey Rastrelli will ultimately be another rider to keep an eye on this weekend. Sitting fifth in points, Rastrelli has proven that he has the speed to take the win after landing a spot on the podium at the FLY Racing ATV Supercross at Daytona International Speedway. Most recently, Rastrelli found himself turning some of the fastest qualifying lap times at the previous round and will look to put everything together to take home his first win of the season.

The 2015 Rookie of the Year and AGX Designs/Walsh Racecraft/Maxxis’ Nick Gennusa heads into this round ranked sixth in points. Gennusa has yet to have a top-five finish, and will look to do just that this Saturday. Following Gennusa by just two points is Root River Racing/Hoosier Tires/Rage ATV’s Josh Upperman in seventh. Upperman finished second at the Ironman National last year and will use that as motivation to find himself on the podium once again.

Joe Byrd Riding School/Honda’s Joe Bryd sits eighth, followed by Maxxis/Liquid Wrench/Elka Suspension/Honda’s David Haagsma in ninth and Koster Racing/Blommel Motorsports/Walsh Racecraft’s Brett Musick round out the top ten heading into the Ironman National.

Saturday’s race schedule is as follows: practice at 10 a.m. followed by a timed qualifying session at 11:30 a.m. Pro motos are at 2 and 5 p.m. with an autograph session taking place at 4:30 p.m.

Saturday spectator passes run $20 for adults and $10 for children (6-11), with kids five and under getting in for free. Each pass includes pro pit access and pro autographs at no additional charge.
