Stadium Medical, Inc. will be providing EMT and paramedic support at all playing sites. Please seek them out for help with any injuries and advice on prevention. At this altitude, it's important to avoid dehydration by drinking lots of fluids and to avoid sunburn by using sunscreen.

MOSQUITO CONTROL. In the past, the mosquito-borne West Nile virus has been present in Colorado. You should protect yourself. Especially during the dusk and evening hours, use DEET-enhanced mosquito repellent and wear long sleeves and pants.


One of the very attractive aspects of the tournament is the locale -- the City of Boulder. Boulder is a special place to visit. It sits at the base of the Rocky Mountain foothills with a population of about 100,000 and is the home of the University of Colorado. Rocky Mountain National Park is about an hour’s drive to the northwest (you can throw snowballs in July) and Denver is about 40 minutes southeast. The pedestrian-only, outdoor downtown mall offers local culture from street performers to outdoor cafes. The many recreational opportunities range from inline skating or jogging along the Boulder Creek path to riding the many mountain bike trails in the foothills.


The tournament is organized and hosted by the Boulder Competitive Girls Softball Organization, an all-volunteer organization. All profits derived from the tournament go to support girls softball in Boulder.
