Temperatures during morning 6am commute (13 miles) have dropped to a staggering 50 degrees (Arizona). I'm puzzled as to which clothes I should wear. If I wear arm warmers, my arms get sweaty within 20 minutes. If i wear a long-sleeve jersey, I'm freeeezing cold for the first 20 minutes.
Is it expected that you can't be a good temperature from start to finish? Should I just start with arm warmers or a jacket and strip them off as I go? Should I just harden the F up and ride in bibs only?
