No doubt. If you take a look at the commuting mileage thread and do some quick math you quickly realize that these guys are doing lonnng commutes. But even as a 'serious' athlete you wouldn't train hard every day, nor would you want to even train every day. But like I said, if you can afford the time then the distance isn't really an issue.
We don't have Texas heat here, but we do have some Canadian cold. I don't know which is worse, but some weeks in January and February I'd have gladly traded some of that cold for the dry heat.
