33Shake Chia Energy Gel 10-pack | Clean, powerful energy with great taste | 100% natural

Relatively low energy density for either size or cost, but a nice natural alternative to sugary gels. The fact that they are dehydrated means that the weight is kept down so useful for long unaided efforts. The packet is quite large once water is added so doesn't fit so well in to smaller pockets. I used some on an ultra and they went down quite easily with little stomach upset. The filling nozzle is quite small so difficult to get water in from the basic water dispensers at the aid stations. They have a strong vanilla taste which is tolerable, but I would have preferred this to have been far milder. Expensive, so perhaps best for racing and not general training. I could see me using these again whereas I will definitely not get any more of the shakes.
