Having Joe Rosa as your twin brother has its advantages and disadvantages. Advantage: you have the best training partner you could ever ask for. Disadvantage: despite running faster than anyone else ever has at Van Cortland Park and several other historic XC courses, you’ve never won a cross country race. Jim Rosa had the 2nd fastest 2 mile time of the year in 2009 and has been training with the only guy faster than him all summer trying to figure out a way to get his first XC win. If he does; it won’t be a small feat.
