Im Not knocking GU, i think its a good product, im just striving to make mine better. Think of this.
3hr race, you take GU every 30min (Look on the packaging it's every 45min - incorrect info.) as per sachet with 450ml water (doesn't say how much water to take with a gel - where did you get the information? It actually 250ml) at R14 a gel. YOu need 6 gels (4 gels only needed) which is R84 (R56) and you need 2700ml (only need 1000ml of water) of water, you only carry 1500ml (Only have to carry a 500ml & 750ml bottle incase you didn't hydrate enough)
3hr race on whasp, take every 45min with 300ml water at R12 a sachet
You need 4 gels which is R48 and only 1200ml water , leaving you 300ml over
When you start to look at it like this, maybe it starts to make sense.
Thanks for your feedback so far, its interesting to see the misconceptions in the market place
