Good morning fellow Primal Blueprinters.

I am a cycling addict and barely started the primal blueprint. I was reading that with this lifestyle I should really tone down on my training. Normally on my rides/trainings I tend to go intense (75% - 90% HR intervals) for at least 2 hours. I would really hate to lower the intensity of my rides. Do any of you have any tips? should I carb up before a ride? Or what can I take along on the ride to get some fuel. I don't want to damage my body or loose muscle tissue.

Any tip is greatly appreciated.
