16.5 miles this morning at 91 degrees. Took 1hr20min. The ride home at 107 degrees took 1hr30min, for a total distance today of 33.1 miles. I made an "oops" on my route and had to backtrack a little. It was pretty damn hot, but I'm used to it. Still went through ~70oz of water on the way home and sweat like crazy! Met a newbie on his first commute this morning and gave him some pointers. Hopefully I'll see him tomorrow just to make sure he survived!
