Create your fundraising webpage and email everyone you know. You might be suprised by who donates.
ASK, ASK, ASK! Many people intend to donate and just need a reminder. Don't be afraid to email often!
If you've directly asked people to donate without a response, try sending a few updates on how your training is going. Also send updates right before and after your race to let people in on your excitement and victory.
Tell your story. People will want to give because they care about you.
Talk about what you're doing! One team member told his barber and the barber made a donation on the spot!
Make business cards or flyers with your personal website address to remind people where to go.
Ask for donations instead of birthday gifts one year.
Start a facebook campaign and update your status regularly until you've raised a certain amount.
Send a letter with a check donation form to people you know won't donate online.
Host a dinner with friends, talk about your experience, and ask them to support your efforts.
It might be difficult for people to make large donations in this economy. So focus on asking LOTS of people for SMALLER donations.
And remember...you're not asking someone to buy a product they don't really need. You're inviting them to join you in helping change lives in Africa. You can assure them that it is money well-spent, and that any amount makes a real difference.
