Quick answers
RaceIndex has a GPS course file for Denver Colfax Marathon 5K, so runners can inspect the route line on the map. Elevation charts and ascent figures appear only when that file includes usable elevation data.
The Denver Colfax Marathon 5K route starts at Marathon Start/Finish line in Denver's City Park (behind the Denver Museum of Nature & Science near the lake); 5K is held on Saturday at 9:00 AM (Girls on the Run 5K starts 10:30 AM). Underfoot, expect a road course. The setting includes city and mountain. Urban 10 Miler covers the final 10 miles of the marathon course, starting at the Rocky Mountain College of Art + Design (RMCAD) campus and finishing in City Park (2.5-hour limit).
Post-race party in City Park features live music, food and drinks on the lake.
