I've been using GU Roctane gels since they first came out around 2009. Over the years my standby flavor has moved from Vanilla Orange, to Cherry Lime, to Strawberry Kiwi, which I've now been regularly using for races and long runs since the flavor debuted. Everyone has their own preference for this type of product. Some like gels with thinner consistency, some with thicker consistency. Some like sweeter products and caffeine, some with less or none of that. But for me GU Roctane gels are what I love. Another part of all GU gels that I appreciate, is the size and shape of the packaging. The more narrow size makes it easier to hold in your hand while you run, almost like how your hand grips something like a pole. This makes it much easier to manage while running, when your grip might not be quite as firm.
