I’ve always wanted to do a Century, which is 100 miles in one ride. (The longest I’ve done is in the low 80s.) I found a map someone made on Ride with GPS that looked great, with lower elevation gain and lots of opportunities for water/snack breaks. I modified it slightly to have it start and end at home, woke up yesterday, and hit the road. It was a perfect moment in that I had a red eye flight later that evening and wanted to make sure I could sleep on the plane. I started at 7am and ended at 4pm, with an hour of that being various breaks for refilling water and grabbing food. I even stopped at home for a quick break about 80 miles in to eat lunch and walk the dog. I felt really good throughout but was really happy to be off the bike at the end of the day. And I slept through the full six hour flight that evening. Success!
