In any sort of running race I (as well as others) have great difficulty drinking water while running, with a tiny bit going in my mouth and the rest going over me. Having spent the last month in South Africa I competed in a few 10k races where instead of using cups of water they use little sachets. Meaning that when you need some you just bite off a tiny corner and squeeze the sachet, simple eh? And therefore you can run along with it and not spill any. Just wondering if anyone in the UK would ever produce something like this.
