If you're interested in walking to benefit AIDS and HIV programs and organizations, why not sign up for the AIDS walk nearest you?
You can register online on each city's website:
Ft. Lauderdale: April 27, 2007 (better sign up for this one soon since it's coming up)
New York: May 20, 2007 (this one is right around the corner too)
The walk is 10 km (6.2 miles), and takes about 2-3 hours to complete. You can become a walker and raise money, but if you don't want to actually walk, you can also sponsor a walker, volunteer to help out with the walk, or donate money.
It's a great way to get a lot of people together to bring awareness towards this horrible epidemic, and to raise money to help the people living with it. Plus, it's also great exercise.
Fits Tips: Get a bunch of your friends and/or co-workers together and make a team. You can motivate each other and have a little competition amongst yourselves to see who can raise the most money. There is no minimum amount of money you are required to raise, but if you set a fundraising goal, you can encourage one another to meet it together.
