About this race

 The money raised from the Rat Race will now go right back to BR athletics in attempts to improve our athletic facilities, keep highly qualified coaching staff, provide equipment for our athletes, provide an athletic trainer at all home events as well as help cover the cost for opportunities for our athletes to improve their skills and abilities outside the typical season. 

This is a fundraising event so in efforts to keep cost low this will not be a chipped event. Runners will all have a BIB and the race will be timed. There are opportunities for individuals to get involved that are not interested in running too, check our sponsorship donations :). We appreciate your dedication and commitment to improving athletics here at Black River, the amount of support and gratitude does not go unnoticed. Only participants registered by April 1 are guaranteed a T-shirt.
