Syracuse biathlon club offers summer training and competition – The cross-country skiing and rifle shooting of the winter biathlon is one of the Winter Olympics’ most popular events, with 37 nations competing the last time in 2010. Fewer people have heard about the summer’s version of the sport – summer biathlon — where competitors run instead of ski the course. It isn’t an Olympic event yet, but it is becoming more popular in Central New York and nationally. A course at Pratt’s Falls Park in Pompey has hosted the summer biathlon national championships twice over the last 10 years. Members of the Syracuse Biathlon Club train on the course.
