I have a 6:30 a.m. assignment for you

Karen is naturally athletic, but she did not become an athlete until about a month ago.

It started in August when one day her brain overheated and took a wrong turn. She decided she was going to sign up for our 3Day Breast Cancer Walk in San Diego. The 3Day starts on a Friday, and the walkers go 20 miles a day until they reach the finish line on Sunday afternoon.

I have had big ideas like that, but they always go away after I lie down for awhile and have a few sips of cool water. Karen did take a cool soak at my suggestion, but when she toweled off, she still had that look in her eyes.

She has connections to breast cancer and the 3Day. Nataly Pluta, her great friend, is a breast cancer survivor and has done the 3Day for the last three years. Each year, Karen and I have driven down to the overnight camp to say "Yay!" to her and give her a bottle of wine to sneak back to the tent. Karen is married to me, and I am a man whose late wife, Meredith, died of breast cancer in July, 2000. Karen has other family, friends and associates who have experienced breast cancer. She made a list of names, 32 when she was finished, and showed it to me.

"These are the people I will be walking for," she said. To the original names, she had added three more: Caitlin, her granddaughter; Addie, Meredith's granddaughter; and Evie June, my granddaughter. The idea being that what Karen did now might mean these three little girls might go through their whole, deserved lives in a world free of breast cancer.

She started off at three miles. Then we drove to Miramar Lake, where lots of people walk, bicycle and skate the five miles around the lake. Off she went in one direction and 90-odd minutes later, back she came from the other direction. I started getting impressed. I walked, too, all of 30 minutes, and then I waited in the car, drank coffee and read the paper. In fairness, I am just getting back on the trail after hip replacement surgery, but I could have all my original parts and be 30 years younger, and would not voluntarily walk 60 miles in three days, or five miles in 90 minutes.

She bought special shoes and socks; socks with toes in them. Weekends came when she left the house before daylight to meet her team and walk 12 or 14 miles somewhere. She would get back at noon with the classic rode-hard look. One day during the week she dropped me at school at 8 a.m. At 1 p.m. my phone rang. "Just got finished," she said. "Dang," I said. I had taught two classes and eaten lunch. All that time, she had been walking a trail at Lake Murray.

Her body was changing. It was more than weight loss. It showed in her skin, her eyes, her smile, her mood. "Just going out for a short one," she would say at 5:30 a.m. Five miles later, she was back in time to take me to work. She shifted from cotton to a kind of garment that wicks away moisture. She had a waist pack, a special hat, a scarf, an iPod, water, other paraphernalia. She was not just going out the door now, she was carrying gear. She looked like a baseball player getting on the bus. I said to her: "You look like an athlete." And of course she was. I told her she was "dedicated," but an hour later decided I had used the wrong word. "What you are, is distinguished," I said.

About a month ago, she came home from a 15-miler looking like she hadn't done much more than a little gardening. "I feel different," she said. "I feel like I've got 15 miles under my belt." She was in a place most of us don't reach.

Last week, she and her team did back-to-back training, 15 miles on Saturday and 14 on Sunday. Her last week has called for only one three-miler on Tuesday, then rest. But she can't rest. She has dreamed about the 3Day every night. She started getting her gear ready on Monday. Today we double-checked it all. "My mind is doing a million things," she said. She is jumpy. She paces. She's in there right now taking a soak. Nothing special for dinner, she says. I hope she can sleep tonight. Before bed, we are going to watch "Chariots of Fire."

I will drop her off at 5:45 tomorrow morning. Starting-line time is 6:30. At 6:30 California time, if you have read this, I want you to go outside and yell, "Go, Karen!"
