Starting in high school at 161' his first year, he discovered how to put the run into the throw and hit 248' in training at the end of his junior summer. One of the very few successful high school throwers to go on to make Olympic Teams, Duncan was ranked third in the world and reached a best of 308'7". A degree in Kinesiology and 10 years of Biomechanics consulting with USATF's High Performance Division have combined with his 17 year throwing career to�give him an unmatched�technical understanding of the event. Year round coaching at the high school, college and consulting with Open throwers have kept his perspectives and learning fresh. Duncan is the only American to speak at the prestigious World Javelin Conference in Finland. His topic is Javelin Flight. Visit his website at www.pocketvideos.com�for more information.
