Pico De Orizaba Infinity Loop, bucle infinito Citlaltépetl, is an extension of the infinity loop concept thought up by Chad Kellogg, originally for Mt. Rainier in Washington State, USA. Originally, thought up as a grand blend of ultra-endurance and mountaineering.

Hi

I would like to send my achievement. I ran around Poland in the self-supported formula. Official borders of Poland according to wikipedia have 3511 kilometers. I am the first one who so thoroughly circled Poland along the borders, adding several hundred kilometers. Many areas were overgrown or marshes or farms were built on the road. So I have to change sometimes track and I ran around farms etc.
