1993 Tecate/SCORE Baja 1000 The Ironman Strikes Again! MEXICALI, Mexico -- Ivan Stewart of Alpine, Calif., climaxed his best season ever in off-road racing Friday night in the midst of a mob of 15,000 cheering Mexican fans as overall winner of the Tecate SCORE Baja 1000. Stewart not only was declared overall 4-wheel champion in his Toyota Special, he also beat all the motorcycle competitors as well with an elapsed time of 13 hours 29 minutes 11 seconds for an average speed of 56.531 mph. The motorcycle champion Kawasaki team of Danny Hamel, Boulder City, Nev., Larry Roeseler and Ty Davis, Hesperia, Calif., was timed in 13:57:23, averaging 54.627 mph. The huge crowds were as much of a story as the difficulty of the 762.4-mile course, which prevented all by 24 percent (70) of the 250 entrants from finishing. Tough terrain was complicated by sporadic downpours that turned high speed stretches like Diablo Dry Lake into skating rinks. Police estimated that mroe than 400,000 persons saw some parts of the race. Bob Gordon, Orange, Calif., and Frank Arciero Jr., Laguna Hills, Calif., finished second to Stewart mor than an hour behind. Undecided class championships were wrapped up byt third-place-finishing Rob MacCachren, class 8 trucks; Dan Smith and Dave Ashley, 4-wheel drive classes.
