The hardest thing is take-off. Once you have it in the air it's not so bad.

The coldest of the air associated with this front is going to slide off to the southeast, so it's not going to drop straight south into Texas.

The course takes its toll. These climbs are the hardest. They're not very long, but there aren't any other races I do where my forearms are cramping and my fingers are locking on me by the end. We're using muscles in our bodies that we normally only use when we're doing a field sprint.

The hardest stones, by degrees, give way to the touch of air.

It's not the hardest, but it's getting close.

Trees breath just like we do, and their lungs were tainted by all this bad air.
