I went to a seminar a while back put on my doctor's office. They talked about several Ultra-Marathon runners that they work with. The time and hours they were putting into running were ruining their relationships. They said it was completely unnecessary for them to train that much. The longest runs they ever had their ultramarathoners do were 20 miles. And marathoners was 13 miles--don't quote me on that one. The benefits you gain from running significantly decreases beyond 5 miles. ---that is running, not biking, obviously.

I'm hoping to do a 100 mile xc bike race early this summer--and there is no way I'm going to get anywhere close to that kind of mileage in training on the road or trails. I'm going to try the shorter rides with intervals training method. We will see how it turns out . . .
