I put my bottle in the freezer for 3-4 hours before heading home last night. It was hard as a rock when I took it out to get ready to leave. 15 minutes later it was all liquid. Air temp of 101° with a heat index of 113° will do that.
On Sunday I rode for a little over an hour in similar temps and the water left in my bottle was almost hot when I got home. And it's supposed to be like this through Saturday.
