Welcome to the 50x50x50 Challenge!

50 Triathlons!
50 States!
50 Years!
Swim, Bike, and Run; Olympic distance*
One Triathlon to be completed in each of the 50 United States
All before I turn 50 on August 11, 2009

Ordinary People can do Extraordinary Things
if they put their mind to it and are willing to put in a little sweat and effort!

It's Never Too Late in Life To Become An Athlete
If I can do it, anyone can!

My name is Dave Mandelkern, and I completed my first Olympic distance triathlon shortly after my 41st birthday in 2000. Since then I have completed over 65 triathlons, including my first full Ironman Triathlon in 2004. I know that I'm probably never going to win my age group, but I believe that I can make up in endurance what I lack in speed. Hence my quest to become the first person to complete a triathlon in each of the 50 United States of America plus the District of Columbia, and to become the first person to accomplish this by the time I turn 50. By doing this, I hope to inspire others to accomplish something they never thought possible (like finish a triathlon or raise money that helps pay for the research that leads to a cancer miracle drug or help a disabled war veteran discover that they can still ride a bike 110 miles)

All For A Good Cause:

My goal is to raise at least $1000 from individuals in each state for charity, and to match the money raised from each state with corporate sponsorships, $2 from corporations for every $1 from individuals. 100% of funds raised will be donated, with no overhead charges. My goal is to donate $50,000 each (50x50x50 again!) to the following three charities that support endurance athletic fundraising programs:

The world's largest voluntary health organization dedicated to funding blood cancer research, education and patient services. The Society's mission is to cure leukemia, lymphoma, Hodgkin's disease and myeloma, and to improve the quality of life of patients and their families.
Created on the belief that people of all abilities should have the opportunity to pursue a life full of physical activity and of sports.
Bringing individuals with and without disabilities together to undertake unique athletic events throughout the world to encourage, promote, and develop opportunities in sports for all people.

This was a five year quest that was completed with me crossing the finish line of the New York City Triathlon on July 20, 2008.

* Olympic distance triathlon (OD) = 1.5km swim, 40km bike, 10km run. In some states, a Half Ironman (HIM) event will be undertaken instead (1.2mile swim, 56 mile bike, 13.1 mile run). If a state does not have an Olympic or Half Ironman distance event, the longest available Sprint distance (S) event will be substituted instead.
