ChiRunner Decreases Marathon Time by 41 Minutes at age 70!
My ChiRunning experience update:
I ran the Virgin London Marathon on 17th April 2011 in 04:22.48. In 2010 I did it in 05:03:01. This year’s time was unexpected. I put the improvement down to the ChiRunning technique. The qualifying time for Boston at my age (70) is 04:30.
