ChiRunning Worked its Magic
ChiRunning has helped me for running in the sand ! When I ran Trans 333 in Niger last November, the majority of the race was in fairly deep sand. The hook with that race was that it was "non-stop". The distance was 206 miles or 333 kms. Therefore, you had to be efficient to be competitive. Your ChiRunning techniques helped me to secure 3rd place- after 60 hours of running in sandstorms, dunes and mountains.
The same held true for Marathon Des Sables and this recent Sahara Race. I was able to keep my legs fresh with ChiRunning.
Incidentally, when I ran the Yukon Arctic Ultra which as you guessed was in snow, ChiRunning worked it's magic there, too !
Thanks so much for an awesome concept !
