Thanks for the tips, it makes sense to me, I’m more or less eating keto 5 to 6 days a week so easing on exercise carbs works out for my diet. It’s a race I need to train for but an ultra endurance race so 10 to 16 hours a day on the bike, slowly grinding most of the time not a high pace race, can’t go really fast anyway with a 50 lbs load and 2.3" mountain tires. However I don’t have time to train for that long so I need a little higher intensity on the training plan, I may try the gravel grinder or Fondo plans.
