Every year, our staff atHalfmarathonsearch.comanalyzes the growth of half marathons in the United States. We recently completed our annual calculations and report Colorado as being one of the top 3 growth states forhalf marathonsover the past year, following California, which usually leads the growth rate year after year due to the state size and population, and a significant year for Oregon as well, leading with 21 half marathon additions to last years total. Colorado added 15 half marathons since last August 2012, and I'm aware of several more coming. ALSO, Boulder added a new full Ironman! It is with no doubt, the beautiful scenery in Colorado attracts both tourists and active residents to these awesome events. Half marathons and other active events like Ironman also bring revenue to small towns and cities, which can be great for businesses. Great job Colorado for leading the way in the Active Community!!!
