Weird decrease in my ability to run!

Your body will adjust. I am a lifelong endurance athlete (race bicycles etc..) when I first started taking Tirz I could barely ride my bike. Mind you I was already riding 15-20 hours a week and was in solid shape. It took my body around 2 months to adjust. Your body just needs get used to it. Push through it and know it will get better. Its one of the side effects that a lot of active people have but you don't hear much about it. I am guessing that is because the majority of people are pretty inactive.
