Radar Run

Cancelled

Radar (Money) Run
Fairbanks Tired Iron!(Course is a 500-600 foot straight, smooth, strip with radar speed equipment capturing all speeds)

Any air-cooled or liquid-cooled, leaf spring production sleds up to and including Model Year 1979 may compete.
Clarification: For Tired Iron Races, sleds produced in 1978 are 1979 MODEL YEAR and ARE eligible.  A sled produced in 1979 is a 1980 MODEL YEAR, and is NOT eligible to enter.

It is not a requirement to enter any other Tired Iron event with the same sled (or sleds) to enter the Radar Run.  NOTE:  You may not enter the same sled in more than one class, but you may enter a different sled in another class, as long as the sled entered belongs in the class it is entered in, and an entry fee is paid for each entry.  Required safety rules apply; helmet, working brakes, clutch guard, operating tether switch, and snow flap.

There are five (5) Radar Run classes:

  • Class A-1:    0 – 340 cc Air-cooled (up to and including 1975 Model Year)
  • Class A-2:    341 – 440 cc Air-cooled (up to and including 1975 Model Year)
  • Class A-3:    441 cc – up Air-cooled (up to and including 1975 Model Year)
  • Class A-4:    All size Air-cooled (from 1976 Model Year, up to and including 1979 Model Year)
  • Class L-1:    All size Liquid-cooled (up to and including 1979 Model Year)

A handicap is allowed within each class, depending on the size and/or year of the sled, in the form of adjusted rolling start speed(s), for example:

Class A-1:
0–340 cc Air-cooled (up to and including 1975 Model Year)
0–250 cc – 30 MPH rolling start
251–295 cc – 20 MPH rolling start
296-340 cc – 10 MPH rolling start

Class A-2:
341–440 cc Air-cooled (up to and including 1975 Model Year)
341–400 cc – 30 MPH rolling start
401–440 cc – 20 MPH rolling start

Class A-3:
441 cc – up Air-cooled (up to and including 1975 Model Year)
441–500 cc – 30 MPH rolling start
501–650 cc – 20 MPH rolling start
651 cc and up – 10 MPH rolling start

Class A-4:
All size Air-cooled (from 1976 Model Year, up to and including 1979 Model Year)
0-340 cc – 30 MPH rolling start
341-440 cc – 20 MPH rolling start
441 cc and up – 10 MPH rolling start

Class L-1:
All size Liquid-cooled (up to and including 1979 Model Year)
0–250 cc – 30 MPH rolling start
251–340 cc – 20 MPH rolling start
341–440 cc – 10 MPH rolling start
441 cc and up - 5 MPH rolling start

Rolling start speeds are displayed using Radar Speed Trailers.  Anyone exceeding their assigned rolling start speed will be docked at a 2 to 1 MPH ratio.  Example:  If John’s assigned rolling start speed is 20 MPH, and he registers 22 MPH on the Rolling Start Speed Trailer, and his top speed for that run was 65 MPH, his official speed for that run will be 61 MPH, a reduction of 4 MPH, so be careful!

Total monies collected will be divided ten (10) ways, and paid as follows:  1/10th of purse to be paid to the fastest radar recorded sled speed “fastest speed” in each class (5 classes x 1/10th purse = ½ of the total purse).  The remaining ½ purse will be divided as follows:  1/10th of purse to be paid to one person from each class (5 classes), to be determined by a chance drawing.  Each entrant’s name will be placed into a hat (including the “fastest speed” winner of that class), and all names will be drawn from the hat; the last one drawn is the winner. (5 classes x 1/10th purse = ½ of the total purse).

All entrants have an opportunity to be a winner, and share in the purse, even if you are not the fastest sled.  The more sleds that participate, the bigger the total purse(s) will be.

Good Luck!!

Special Note:  Fairbanks Tired Iron guarantees each Radar Run winner’s pot to be at least $175.00!

There are no Radar Run entry fee refunds, period.  Each entrant must complete two (2) runs to be eligible for the “fastest speed” purse payout, but, even if an entrant scratches, without completing one or both runs, they will still be eligible for the “chance” hat draw for the class they had entered.
