Yes,  National Geographic has some very interesting horse videos.

This is one of the most amazing horse races of all-time. If you are not a Thoroughbred fan, you will still marvel at the superb performance of this amazing stallion. This win in the Belmont clinched the title of Triple Crown Winner for Secretariat.

Only a handful of horses have ever won The Kentucky Derby (1 1/4 mile), The Preakness Stakes ( 1 3/16 mile) and The Belmont Stakes (1 1/2 mile). Being able to run and win at all three distances is a feat in and of itself.  Not only did Secretariat win at all three distances, he set a new track record in the Derby, a new track record in the Preakness and a new World record in the Belmont.

Secretariat set that New World Record for 1 1/2 mile on the dirt in 2:24 by running the first 1 1/4 mile in 1:59 which was faster than the his own Derby New Track Record time of 1:59 2/5. 

In addition, Secretariat won the Belmont by 31 lenths. You can see this amazing race on YouTube at
