The lost 🗺️ Red Rock Loop in Gravel Mountain reappears! The Gravel Mountain world was a test apparently abandoned by Zwift, but still available as an "event only" route. The WTRL duathlon used it today, so I rode it (though I did not run). The route is rather nice for gravel and reminiscent of home: mostly flat gravel with some short sharp climbs. The landscape is southwestern, with elements of the desert, jungle and Mayan worlds in evidence: stone arches, flame pots and waterfalls. For the official 35 minute "time trial" Zwift Power gives me an average 1.9w/kg or 136w (139w normalized). I did a final cool-down lap in granny gear as a tourist, stopping to take pictures at points. The overall ride was then 18.5km at about 112w or 1.6w/kg, by Garmin. I worked around my still unsolved BT issue by cabling the run PC to the soundbar. I can now stream YouTube video playlists over filtered Firefox. That will be important as I plan to do longer rides up the mountains.
