I’ve been a fan of the no sugar nuun hydration tablets for a few years. They solved my cramp problems that I developed late in 2009 racing when for example this http://www.stodgell.co.uk/?p=859 happened. I always sip on a bottle with a nuun tablet in on the way to events to make sure I am not only hydrated but that my salts balance is correct before starting. Last week I entered a retweet competition on Twitter and won! My prize turned up this morning, a nice Nuun water bottle and a couple of tubes of Nuun in Strawberry Lemonade flavour. Thanks nuun!
