The run starts promptly at 9:00am MT for all dates in October through May and 8:00am MT for all dates in June through September.
The bus service in the area, the Regional Transportation District (RTD), makes it easy to get to SBC parkrun from anywhere in Boulder or Denver. Their schedules are integrated in Google Maps. If you're coming from Denver, the easiest option is to take the FF1 bus to Table Mesa Park-N-Ride in Boulder, then walk the mile-or-so from there to where we meet for the run.
