Hi all - have decided to dip my toes into keto due to a very recent decision to sign up for a marathon.
I’ve given myself 21 weeks to train up (slightly longer than recommended, but I’ve little experience in long distance. Also, I’m a nutter). Having heard about the ‘crash’ that occurs at mile 20ish, keto seems like the obvious way to avoid such a pain.
However, I’m a little nervous about whether all of this is too much at once - should I delay on the keto (after all, getting the dreaded keto flu whilst training would be a frustrating set back), or should I just jump right in?
(Also any long distance running advice/anecdotes would be greatly appreciated) x
