"I tried this protocol in the weeks leading up to Ragnar. I picked up the training and was running a couple of two-a-days to practice running fatigued. So I used the EnduroPacks I received to help my training. I ramped up my mileage by quite a bit during those weeks, more than the typical 10% rule would call for. But I found that my energy levels were high and I didn’t feel any soreness or fatigue from the additional training. I can’t help but think it was due to the supplementation I was getting from the EnduroPacks."
