You imagine running 120 miles a week, week in, week out, for the past four or five years. It takes a little bit out of you.
I have been through various fitness regimes. I used to run about five miles a day and I did aerobics for a while.
When I'm not running, I cycle about 30 miles a day. I use the biking as cross training. I'm kind of a maniac. I race everybody.
