I'm still way too heavy, but I am much more fit than I used to be and 40 pounds lower than my peak weight. My diet is Keto influenced, but includes normal servings of carbs the day of and day before hard exercise. I tried long bike rides while doing kbeto, I'd be exhausted after 15 miles. I'm going to eat a baked potato, bread to go with a lot of meat Friday night before I do the HHH 100K bike ride Saturday. I'll eat and drink all kinds carbs on race day. I won't be a top finisher, but there won't be a lot of guys who weigh 250+ riding hybrids ahead of me.
