For me drinking enough liquids is always a challenge. I’ve started taking sips every 10 minutes to make sure I at least get through at least a bottle an hour.
I like Maurten powder and gels. If it’s hot I have no issue getting through bottles. But I also like untapped waffles and their syrup.
My waist pack has 50oz of plain water so I can add that as well.
So I will likely use Maurten drink powder. I will eat some salty snacks at the checkpoints.
I have a lot of practicing to do between now and race day as nutrition is a challenge for me
