Sufferfest. Boy did I mess this up. I was exactly on target until around mile 19 or 20, when everything became remarkably difficult. Pretty sure the wind made the heat feel okay, but the humidity made me lose a lot of water and salt. Cramped around mile 21. Stopped to walk a million times. Missed my goal by over 15 minutes.

My plan was 17 minutes at 235W, my easy warmup pace, then four 6-mile laps at 259W (adjusted down from 261W due to weather), then 90 seconds at whatever i could do to cross the finish. I nailed the first three but it all went downhill from there. My average power wound up being 241W, worse than SF in 2019.
