We had a road closure that altered our course to 262 miles. I was DNF at mile 201 and about 14'000 feet of climbing completed. The ride started at 0500 with temps in the low 40's. Rain began around mile 90, and it stayed cold. I was dressed correctly and never got the chills, but obviously speeds were down tremendously. At mile 120, we needed to stop for hot food, which was a challenge. At mile 150 I did the mental math that our completion wouldn't be until 11:30pm. At mile 170 my legs were fine. I was never really "exhausted" on the ride, but darkness was looming. I lost confidence in my ability to safely handle the bike on very dark/wet roads, especially knowing there were hours left to go. In one of the worst moments of my short cycling history, I SAG'd out at 201 in the cold rain. The attrition on the full ride was high (9 started, 2 finished). I should have been a finisher, but my heart and head got in the way. Today is pretty bleak. I let down my friends, and I let down myself. This wasn't about fitness and there's no amount of trainer/roller work that can possibly help me for "next time". For now, I'm just going to focus on the trainer and try to learn from my failure yesterday. I have a lot of things ahead in 2018 -- Haute Route Asheville (3 day event), another 200-mile ride to the beach, and a host of single-day stuff.
