Road Closures

The 11th running of the Colfax Marathon will have temporary traffic impacts along West Colfax Avenue in Lakewood on Sunday, May 15, 2016. While travel on Colfax Avenue will be restricted, normal traffic patterns will resume as soon as it’s safe for athletes, spectators and motorists.



Lakewood is one of the proud originators of the Colfax Marathon, now in it's second decade. Last year, Runner's World  called it one of "10 Marathons to run," and now in 2016, one of "10 Great Marathons for first timers."
