Fivefingers- Day 3 run

Today I was not enjoying my fivefingers. Calves killed me today when I ran. Everything that I have read says this is normal when you first start out. It was extremely hard to run. With the mud run coming up I cannot afford to decondition while trying to get adjusted sooooo I am going to use them only once a week so I can go back to my normal running mileage. Going to order the Nike Frees to train in for now. Still plan to wear the fivefingers to the gym and one short run a week until after Sept 25
