What type of gatorade bottles are typically handed out at aid stations on the bike course? In the few triathlons I've done, the bottles have been the 24 oz type with the sport top cap which fit (somewhat loosely) in a bottle cage. I did Calgary 70.3 this past weekend and was surprised to find the gatorade bottles they were handing out were the smaller 20 oz type with no cap. This would be great if I had a refillable BTA bottle, but I don't. When the volunteer handed me a bottle with no cap I wasn't sure what to do with it, so I just took a couple big swigs and tossed it before I was out of the drop zone.

Just curious what bottles are typical when Gatorade is the on-course hydration.

Thanks.
