Did my first Metric Century yesterday in Southern MN. Started out a little chilly, but warmed up to mid 60s. Mix of gravel and country roads. By about mile 50, I was feeling it and wanted to be done, but completed the mission. My goal was sub 4 hours, so I barely missed it but still extremely proud and extremely sore!
Congrats! Good job on sticking it out when you were feeling rough after 50!
