Tried the Orange burst for the first time on a 1/2 Marathon. I was truely amazed. I never lost my edge. I took it at the begining and at mile 8. Just was impressed with it for the little investment, how big of a difference it made for me. I will be using it more often for my longer races.
I drink way too much water and was told by my doctor to drink more electrolyte drinks, but they just aren't convenient for me. These tablets are easy to carry and plop in my water bottle. Also, for long runs where I refill my water bottles, this is much easier to add a tablet to than to just have water all the time (I refill at drinking fountains or people's houses). They taste great too.
I find my recovery is better when I have one after a long run as well.
Bottom Line Yes, I would recommend this to a friend
