I wanted to submit this here mostly because it is the first time the 53 Classics have been completed in winter, as far as I know. I expect the 53 Classics will be done MUCH faster as early as next fall (note that 20 of these climbs are closed for nesting raptors Feb 1 - July 31).
After doing Roach's Top 10 Flatirons climbs in 11h27m on 1/4/2020, I decided to try to get the rest of the Classics done in January. I tried to take advantage of the dry weather in early Jan, but life intervened some days. We had a string of mild (generally below 40 degrees while I was climbing), dry days mid-month, and I was able to get out each day and finish off all the climbs. One thing I learned is that even on a cool morning the rocks are warm pretty early if there is strong Sun. On the 11th when I topped out on the Seal it was 28 degrees at NCAR, but climbing w/o gloves was OK. But, each day at 1pm the Sun goes off the rocks and it was immediately cold. All climbs were done alone. I did the following linkups for this project.
