Oh, Elaine, thanks for asking! I was going to post something about it today.
It was a fantastic experience. There were 5300 walkers. They did about 35 km on Saturday, and then 25 km on Sunday. Although it wasn't a race, on Saturday, she and the girl she was walking with were 323 and 324 out of 5300 through the "finish line". She wasn't sure of her placing yesterday, but figures she was somewhere in the 800 to 900 group.
They raised $17.2 million dollars over this weekend. Apparently that's some kind of world record. She was tired and sore last night, but euphoric!
