Some great feedback just through:
I recently supported an Oxfam crew doing the 100k walk/run and witnessed one of the team members struggling with severe cramps and dehydration at a checkpoint.
He had never taken Fizz before, but was made to drink some by another team member and take some with him.
He walked off with the aid of his team members and then remarkably ran in at all the 3 remaining checkpoints, without any signs of cramp.
I tell friends I witnessed a miracle that day. A great endorsement for your product.
