Love the watermelon lime.

Love the watermelon lime and the caffeine boost is icing on the cake. All Glukos product have been easy on my gut. I primarily use the fruit punch for training and races and add caffeinated watermelon lime in at specific intervals. This is working for me. I may take something additional if the miles are really looooooong, for calories and to get some solids in me to take me that special long distance( think marathons and ultras) . It’s working perfectly for me and my friends as intended.

Great taste, energy on demand

Glukos provide a great alternative to eat more energy bars. These go down very smooth and taste great.

I got samples of these when I bought some Nathan products and gave them a try on my next long run. I loved these so much! I bought three boxes and use them on all my long runs and have shared with friends too! Big fan!
