I have been taking those plastic refillable GU containers and filling them with maple syrup. Each container holds 1/2 cup of syrup which yeilds 400 calories. That is the calorie equivalent of 4 GU packs. To say this is a cheap replacement for GU is an understatement. I buy the maple syrup at Costco in bulk. Since maple syrup is pretty much straight glycogen, it also has a very high GI rating which shoots insulin levels through the roof and back. I only use this on epic rides (to constantly throw fuel on the fire while riding). Do you see a problem with this?
