I don't really understand the logic in using running marathons to get money for diabetes. Unless you are very, very careful, most people who run marathons can easily get blisters on the feet or develop many foot problems from pushing themselves to run for miles and miles.

Somehow it seems a little like selling sugar filled candy to get money for diabetes. The action that gets the money isn't exactly the greatest thing for people who have the disease.

I can see maybe walking for diabetes, and there's no winner for the fastest. Just a win for everyone who finishes. I can see any sport that is gentle and won't hurt the people with the disease who enter the fundraiser. How about golfing for money? Swimming? Biking? Dancing?

Why running? Is it the most popular sport?
