2022 2.4 Hour Great American All Star Endurance Challenge Race
International Sportscar Federation (ISF), Indyslotcar, SHMUC (Super Hot Mod Unlimited Championship), American Racing Alliance (ARA), and other racing world stories by esteemed commentator: Steve "The Wrench" Ratchett
The 2022 ISF season started with the most grueling event, the Great American 2.4 Hour All Star Endurance Classic Race on the streets of Rapids International Raceway. Dean Strom and Mike Lack were randomly paired for the second time in the history of the race, were the winners by 10 laps over the team of Matt Hayek, Joe Heitz, and Steve Rist.
The fifth segment started with Strom-Lack having a two lap lead over Hayek-Rist-Heitz. It was not a strong segment for the second place team as they fell further behind. It was the strongest segment for Wiedemann-Kristof-Black as they kept pace with the leaders and made a serious dent into the gap to the second place team.
That set up the sixth segment which saw all the teams struggle as several cars lost at least one shoe. That brought Hayek-Rist-Heitz back into contention and at the end of the sixth segment and throughout the seventh they fought to within five laps of the lead until the end of the penultimate segment when they were 10 laps off the lead.
The final segment saw Heitz start against
Strom and initially Heitz gained two laps until his tires went off and Strom
found his speed comfort zone and picked up the pace. Heitz changed with Hayek
and Strom changed with Lack but Hayek couldn’t catch him and Strom-Lack took a
well earned win (1,321 laps). Hayek-Rist-Heitz finished second (1,310 laps) eleven laps down. Wiedemann-Kristof-Black finished third (1,226 laps) and Dorn-Kamikawa-Core
fourth (1,196 laps).

Children Racers
Children, under the age of 16, but at least 10, who
are directly related to an ISF member (i.e. son, daughter, nephew, etc.) may
race in the GTP, F1, GT & LMP categories if they can meet the following
criteria:
1
-- their best qualifying lap is within 120% of the polesitter's time
for
example, if pole speed is 6.545 seconds, a time within 120%
must
be under 7.854 seconds
2
-- they had no more than two offs during their qualifying run
3 – they
can run at least two minutes at speed with three offs or less
These rules have been set to be sure that young racers
can show two things: good car control and good pace
The ISF founders felt that 120% would be a
reasonable mark for pace, and more than two offs in 12 laps would be a bit too
much
Rules apply to children racers until they prove that
they can meet these criteria on a consistent basis.

-Different
brands of cars may be allowed modifications to help equalize the field at discretion
of ISF commissioner and test results
