I first tried Gnarly at one of the Vacation Race series races, and was amazed at how good it was. When I decided to run an Ultra Marathon, I knew that I needed Gnarly to be a part of it! In trying to decide the best way to carry Gnarly with me for aid station refills, I came across the single serve packets. These were life savers in the race! Light enough to carry with me, and packing enough punch to keep me hydrated and enabling me to complete my first Ultra!
