Dear Danny and the Chi staff,
In May 2009 I weighed 334 lbs and started a walking program. I slowly introduced jogging in September, 2009 and have steadily increased my distance and pace. Today, I weigh a bit less than 200 lbs and will run my first marathon in 30 years on Sunday.
In January I started transitioning to a mid-foot strike using the ChiRunning book and DVD. This greatly helped my knee issues. Thank you for your help.
