15 mi ~ 1.5 hrs.
Felt like a looooong ride. I decided to ride from the house to the bike trail (which is the added 4 miles round trip). I didn't realize just how hot it was. But I got a good 5 miles of dirt trails in and the rest was on the bike path. I did buy a new mini hydration pack that is awesome. Pretty sure it's probably a kids pack, but it was red and it fits ... so that's what I got.
