Powder mix or squirt into a water bottle. This allows you to manage your energy intake and doesn’t sit in your stomach like a gel.
Price ranges from $2.99 to buy one get one free if you can find it. Assortment of flavors. Stock up.
I use this on both short and long runs. Gets me moving quicker. Best to have a normal bottle of water and then a 2nd bottle mixed with this. Easy for on the go and low cost.
