So, the day after the first ride with the new Garmin 810 didn't go any better and, in fact, was worse than the first time. Still have two "rides" since I noticed a few miles in that my bike profiles went "poof" and disappeared for my most used bikes and the cadence sensor wasn't registering. Plus, I was still tired from yesterday's sloggy, cold, hill-climbing ride and my knees were still very painful. Did not make for a very efficient or effective ride. Oh, and I was late too so I was trying to keep up (didn't work) and then navigate sans cue sheet. Yeah, a bit of a cluster. Luckily, the gang was very, very, very accommodating and the after-ride was quite enjoyable. Needless to say, I'll be making an appointment with the orthopedic surgeon forthwith. But other than that, it was a great day! ;)
