Hey Tabby and warneral, thanks for asking
First I allowed myself some slack (regarding eating and sports) if I had to and tried to keep eating healthy the rest of the time As far as I can tell it didn't hurt my goal to lose weight too much. After relaxing a bit it didn't take to long for the cravings to stop.

We had really bad weather since August, so we had a bike-break and had to do more running. Because running the same old route over and over got boring, we started searching for a new one and found a very nice track in a forest quite close to our apartment. There is an "official" training route at half marathon distance but even more appealing for me are the many little pathways through the forest. Running through the rainy wood on soft dirt paths has been so much fun I hardly noticed that I had increased my running distance to about 7-8 km per run after a while.
Last week the weather got a little better and biking was a lot of fun after the short break too Somehow, DH and I have inspired my brother-in-law (who never did any kind of sport since I have known him) to buy himself a MTB and go riding almost every day and he was so beaming talking about his new passion that some of the inspiration somehow came back to me.

It wont help you to say that once you start to eat healthy again you will soon feel better and have less cravings than while eating unhealthy, will it? I know it's hard once you are stuck in this cycle.
