I just found this video on YouTube, posted by one of the researchers who visited SP Kennel in January to do physiology research. The description reads:
This past January I went to Fairbanks, Alaska to do a research study on sled dogs. Their ability to cover long distances with minimal rest is a physiologic phenomenon. For our study we went to Two Rivers, Alaska and performed our research on the sled dogs of Skunk’s Place Kennel. SP Kennel is owned by Aliy Zirkle and Allen Moore, two of the best sled dog mushers in the world. Aliy has won the Yukon Quest and has competed in the Iditarod 9 times. Allen has won the Copper Basin three times and has competed in several Iditarods.
Thanks for the great video!
