Resolves YES if I bike at least 100 miles in one broadly-continuous session by the end of 2026. I'm allowed to stop to eat and drink and go to the bathroom, but not to take an extended break from biking (>30 minutes).

I rode for 50 miles recently without using any food and fairly limited water, and not doing particular prep for it. By the end I was definitely hitting the wall a bit but I was totally fine afterwards once I had some food in me. I'm biking fairly regularly but training for long rides is definitely not my top priority.
