i typically do more jujitsu/lifting/crossfit but occasionally other kinds of events. There is a 100 mile relay race (teams of 4-6 people in March (so i would end up running about 20-25 miles give or take). Given being carb sensitive and now eating more of a real food keto/carnivor-ish diet do you have suggestions or insight on how to fuel for this? I would like to test somethings out prior in training and just need some ideas to get started.
