When I use to live in the Mojave Desert area of Calif I use to fill one Polar bottle with my chilled Gatorade mix almost full and stuck it in the freezer overnight so it would freeze solid, this bottle would remain frozen for 2 to 2 1/2 and be ice cold for at least another hour past that. That frozen bottle was one of three bottles I took and would use that bottle for my last bottle. The other two I would fill one (I put empty bottles in the freezer overnight) with ice then pour chilled Gator into it and that was my second bottle to drink from. Then my last bottle I would fill about 1/2 ice and pour in the chilled Gator and drink that one first.
I also carried a Camelback on my back for longer rides and filled the bladder with ice then put chilled water in.
