With pledges, participants ask donors to pledge a dollar amount per mile or kilometer. Then, the donor will give based on how far the participant was able to walk. For example, a donor may pledge $8 per mile, which would result in a total of $40 if the participant runs 5 miles.
Pledges can encourage your attendees to put their all into your walkathon, since donations are on the line. They can also lead to larger donations, as donors may be more willing to pledge $10 per mile than pay $100 out of pocket.
A pledge fundraising model works best on a closed circuit course, so that participants can keep walking to rack up miles. Be sure to provide lap cards, so that supporters can easily keep track of their distance.
Pledges motivate your participants to push themselves during the walkathon.
