We were testing the "pavement only" route from our house to the Flying Star north of Griegos on Rio Grande Blvd. Here's the route map from Map My Ride:
It's 4.7 miles round trip on the bike path or low traffic side streets (mostly San Isidro). There was a few hundred feet on Candelaria and another leg on Griegos from San Isidro to Rio Grande. The video below #throughglass shows the bike lane on Candelaria as we approach the Rio Grande Animal Clinic.
On the way back we turned early off of Griegos and got away from the traffic by detouring past Our Lady of Guadalupe Church. In retrospect, it's probably better to take the little bit of gravel ditch-bank road between Griegos and Dietz Place NE, which brings you up to the back of the Flying Star. That would let you miss the traffic signal and congestion at Griegos and Rio Grande.
Here's the view as we finish up on the bike path next to the Alameda Drain.
