Embrace the winter

 Training in "adverse" conditions actually makes you a stronger runner. I mean, we all knew this after the 100 degree, 100% humidity summer we all suffered through. But the same also holds true for the winter. Running on icy roads in the wind and cold builds running and core strength, flexibility, total body awareness, and mental toughness. While this is good for base training, and even maybe a little bit of tempo work, it's hard to keep any sort of pace on a dark, slippery road. So, although many of us hate it, running on a treadmill for hard workouts every once and a while isn't the worst idea in the world. Other cross-training options such as spinning, swimming, cross country skiing, and snow shoeing are also good for mixing it up.
