One little adventure to share:

I had charged my trust Garmin Edge 130 Plus for the ride, however, its battery died at about Mile 90. "No problem," thought I. "I'll just finish with my phone." I dug my phone out, only to find that it had discharged itself down to 15% looking for service. I forgot to put it in Airplane Mode. Wanting to save the rest of the charge for possible emergencies, I turned to my watch, on which I had luckily uploaded the medium course, which finished the same as the long course. I was able to finish with my Garmin Instinct 2 watch. The only downside, is that I didn't get credit for a proper century ride and Strava doesn't know it was one ride. Bummer, as I don't do epic rides like this too often.
