On the ground — what to expect
The leg clocks 45 road miles via Peña Blvd → E-470 N → US-36 W. Typical drive-time clusters between 50 and 90 minutes. CU / St Julien / Pearl St. US-36 is tight both peaks — budget 90 min for a 7-9am Boulder arrival. Flight tracking fires on wheels-down, so the sedan is already queued at Denver International's pre-arranged ground-transport kerb when the first checked bag drops onto the carousel. Common drop-points inside Boulder: CU Boulder, St Julien, Pearl Street, Chautauqua.
