Re: New 13 y/o distance record - 735 feet (224 meters)
That throw was quite a bit farther than we expected. We've been practicing a lot and I hoped for something in the 650-680 neighborhood. Three factors made it longer I think.
1. Excellent throw early on so the arm was fresh.
2. Excellent disc - the lightweight Pro Boss was perfect for this
3. Excellent conditions - wind speed at release was 17, but it probably gusted somewhat higher during the throw. Altitude +/- 3000 feet. It was chilly though, in the 50's, so that aspect could have been better.
Mark Jarvis, who we know can throw that far, threw his long throw first, and David's mark was not too far from that. If not for that and the fact that we measured the throw numerous times with different people and two range finders it was enough beyond our expectations that I might have suspected a measuring error.
He'll have his work cut out for him to top that distance next year. Continued growth (He's about 5'8" ,140 lbs now) should help.
