I posted a comment left yesterday. A natural running drink. Good idea. I'm sure I will try this. Thanks!!!
Hi Alyson, I am also training for the Ottawa Half. I didn't want to use Gatorade for so many reasons including some of the ones you suggested. I found some great recipes for easy home-made drinks. For the last few longer runs (between 13 and 17 k) I have been drinking a combination of:
2 tbsp lemon juice
2 c water
1 tbsp agave nectar
sea salt to taste
It's delicious, refreshing and I feel great. A running coach also suggested replacing the agave and lemon juice in the recipe with just a half a cup of fresh squeezed o.j.
