I started Atkins a little over 2 weeks ago now and the weight has been falling off. One problem I am experiencing surrounds my running.

I've been running for a few years. Over the past year or so, I put on about 20 lbs because of a major back problem which has since healed, as well as a very bad year emotionally. I had started running again about 3 months ago and was progressing well - up to about 45 minutes duraction for 5 or 6 days per week. (usually, my runs are 30-35 minutes.)

Since starting Atkins, I'm finding that my legs get sore and tired within 5-10 minutes of starting my run. Usually, by 25 minutes, I'm ready to stop. Yech!

Any advice from anyone would be greatly appreciated.
