May I interest you in The SMART Ride
from South Miami to Key West in November? The details are in the link below, and it's not too late to sign-up, especially if you're a regular cyclist who doesn't need a long training period for the 165-mile distance over 2 days.
100% of all the money raised by the riders goes to 6 HIV/AIDS non-profit agencies in Florida. The operating overhead is covered by corporate donations, from the likes of Target and Starbucks, plus many local Florida companies. Even the organizing committee (my partner is a founder of the ride and on this year's committee once again) takes no salary or compensation, unlike some other charities.
Here's the link, and you may email me with questions. As it happens, I'm doing some of the room assignments for the overnight stay on Marathon Key this weekend! But it's not too late! And I'm a rider myself.http://thesmartride.org/3/
