Hi low-carb friends!

I am very new to this LC thing. I started Atkins a couple of weeks ago, but only got through a few days of Induction and did not feel well...absolutely no energy. I know this is supposed to be normal and go away eventually. HOwever, I was planning a long bike ride (60 miles) and wasn't sure if I could make it. So I started adding a few carbs. I got through that ride fine. But yesterday I went on a longer ride with a difficult hill climb and I felt like my legs had no staying power. I had to walk a lot of the hill. That is a first for me. I am very active (cycle 30-50 miles, 3-4 times per week) and don't want my favorite exercise to be compromised.

Any suggestions would be greatly appreciated.

Thanks
