I did some VO2 max myself this morning, 5x5'. Rather than go to Fiesta Island, I found a quite neighboorhood hill about ~15 min ride from work, perfect. The hill is very steep and flattens out near the top, giving me an opportunity to switch into the big ring for the final ~90 seconds or so.
It's purely resitential, quiet, wide and has vast sweeping views of Mission Gorge and Mission Trails off to the right (east). It's perfect for VO2 max work.
