Day Four: Magnificent 7. We’ll start today’s ride from the bottom of the Gemini Bridges road, where you’ll get a nice long “warmup” of about 5 miles before hitting the actual Mag 7 trail system (specifically Arth’s). The singletrack climb will be techy and gradual, with plenty of tough/tight moves to keep things interesting. At the ride’s virtual half-way point, we’ll turn around and come down Bull Run, Great Escape and Gold Bar, all moderately-challenging descents in their own right. Be sure to save some gas in the tank for the short’ish climb back out of Gemini Bridges, before heading down the home stretch. Today’s ride will be 28 miles with 2500′ of climbing.
