Pima County's newest BMX track, Xtreme Fun BMX track at Mike Jacobs Sports park, west of I-10 and south of Ina Road, is celebrating its grand opening with free racing Saturday, starting at 9 a.m.

After the grand opening ceremony, attendees will be able to tour the park, attend free race clinics, race or watch races. 

The operators of the track, Julie and Kirk Vaughn, have turned 18,000 yards of dirt, courtesy of the Pima County Ina Road Wastewater Reclamation Facility, into 1,200 feet of BMX track.

The free racing day is also in honor of Olympic Day, which commemorates the first International Olympic Committee meeting in Paris in 1894 and the founding of the modern Olympics.

Racers must wear long pants, long-sleeved shirts, helmets, closed toe shoes and bring their own bikes. They must also sign a liability waiver.

Food and drinks will be available for purchase. 

The County plans to connect Xtreme Fun Spot to The Loop, the system of bike and pedestrian paths being developed around Tucson, so BMX cyclists will be able to get to it from other parts of town, and will be able to travel between it and Kory Laos BMX Park.
