[22]Well, for those of you who have seen the picture in the little biography—it might have given it away—I’m a person without legs, and I was born without particular bones in both legs. I was operated on and lost both of my legs at age one and I’ve been running like hell ever since, all over the place.
    I guess I’ve always been involved in sports. I played softball for five years growing up. I skied competitively throughout high school, and I got a little restless in college because I wasn’t doing anything for about a year or two sports-wise. And I’d never competed on a disabled level, you know—I’d always competed against other able-bodied athletes. That’s all I’d ever known. In fact, I’d never even met another person without legs until I was 17. And I heard that they do these track meets with all disabled runners, and I figured, "Oh, I don’t know about this, but before I judge it, let me go see what it’s all about." So, [23]I booked myself a flight to Boston in ’95, 19 years old and definitely the dark horse candidate at this race. I’d never done it before. I went out on a track paved with crushed stones a couple of weeks before this meet to see how far I could run, and about 50 meters was enough for me, gasping. [24]And I had these legs that were made of a wood and plastic compound, attached with Velcro straps—big, thick wool socks on— you know, not the most comfortable things, but all I’d ever known.
    And I’m up there in Boston against people wearing legs made of all things—carbon black lead and, you know, shock absorbers in them and all sorts of things—and they’re all looking at me like, OK, we know who’s not going to win this race. And, I mean, I went up there expecting—I don’t know what I was expecting—but, you know, when I saw a man who was missing an entire leg go up to the high jump, hop on one leg to the high jump and clear it at six feet, two inches... Dan O’Brien jumped 5’H" in ’96 in Atlanta, I mean, if it just gives you a comparison of—these are truly accomplished athletes, without qualifying that word "athlete." [25]And so I decided to give this a shot: heart pounding, I ran my first race and I beat the national record-holder by three hundredths of a second, and became the new national record-holder on my first tryout.
