Best Fuel I've Ever Used For A Marathon

I've tried all kinds of gels; they're all too sweet, too thick, too messy and they upset my stomach. Now I mix 2 scoops of Roctane powder (a little more carbs than 2 gels) in a 20 oz bottle of water and I'm good for 8 to 12 miles. For a marathon I carry 2 extra plastic bags of powder which I mix with water at an aid station as needed. It may not be quite as convenient as a gel, but for those of us who don't tolerate gels well this is perfect, not too sweet, not too thick, tastes great.

For that unstoppable feeling

I use this mix on every ride now. At first I was afraid that I would feel the affects of too much caffiene but it doesn't create a 'buzz' but more of a constant flow. I take drinks from the bottle every 5 minutes and my legs feel great during the ride. A noticable decrease in the feeling of fatigue. I've also noticed that my recovery time has reduced after long rides as well.

Better off with the GU packs

I used this product on several long runs and after only a few miles it started to make me sick. This product doesnt seem to mix well with water and even less with the human stomach. I think you're better off with the GU packs and use another hydration mix.
