The Lyons River Run is part of the Boulder County 4-Race Series. The 4-Race Series highlights events
around Boulder County with some nice prizes. Each event is independently operated. They each have their own community feel,
organizers and beneficiaries, but have joined together to promote each other and offer prizes for the series, in addition to the prizes
at the individual races. Come and try out some new and different events. This year’s 4-race series events are the Run Like the Wind
in Allenspark (July 22nd), the Sunrise Stampede in Longmont (August 12th) and the Erie Eerie in Erie (October 28th).
