fundraisers

The Krispy Kreme Challenge Children's Specialty Clinic gets its name from a student-run charity race in Raleigh, N.C., that has already raised $1 million for kids. Still, some find the name unhealthy.

Some of the largest, most established walkathons and similar events that raise cash for charity aren't doing as well as they used to. There's more competition, fundraisers say, for money and time.
