Thanks, Scott! I actually was a graduate student in UCDavis in 1998-2002, so it brings back some memories. However, Davis is not considered a part of SF Bay Area, it’s in fact close to Sacramento. I can see how it was convenient for Adrian Ballinger to get tested there rather than drive further. I wonder if this test is what you recommend: https://www.fitnesswavenorcal.com/pages/vo2-sub-max/
Thanks a lot!
