Marsh Madness is an annual running and walking event. With the joint partnership of the Palo Alto Family YMCA and Lucile Packard Children's Hospital. Our 7th annual 5k/10k and ½ marathon run/walk will take place in 2014.

100% of funds raised go to enhance, advance, and provide access to programs that help local youth and teens be healthy.

Marsh Madness is part of the Palo Alto Grand Prix race series.

Due to extensive flood control work that directly impacts our race route, the Marsh Madness event will not happen in 2013. Please join us in 2014 for the 7th Annual Marsh Madness.

Thank you to our 2012 Marsh Madness Sponsors
