The Sand Creek Regional Greenway Partnership and Bluff Lake Nature Center are hosting our inaugural Race for Open Space 5K Walk/Run and Earth Day Festival on Saturday, April 20!

The beautiful course will wind along Sand Creek through Denver and Aurora, and finish with a loop around Bluff Lake. 

Note:  We are showing solidarity with our fellow runners and spectators in Boston by giving out blue and yellow ribbons – the race colors of 2013 Boston Marathon – on Saturday.  Join us on Saturday to declare, “The race will go on!”

Sand Creek Regional Greenway Partnership

About the Greenway

The Sand Creek Regional Greenway is a jewel in the necklace of trails that has made Denver a national model for linked trail systems.

This 14-mile public greenway connects the High Line Canal in Aurora, Colorado with the South Platte River Greenway in Commerce City. Along the way, it passes through northeast Denver and the new Stapleton community.

The Sand Creek Regional Greenway is open every day from dawn until dusk. Runners, walkers, nature viewers, horseback riders, and leashed dogs are encouraged to enjoy the trail. We invite you to become acquainted with our wilderness in the city.
