walkathon

A walkathon (walk-a-thon), walking marathon or sponsored walk is a type of community or school fundraiser in which participants raise money by collecting donations or pledges for walking a predetermined distance or course. They are similar in format to other physical activity based fundraising events such as marathons and cycling races, but are usually non-competitive and lower intensity.
