Up to 35 miles an hour. very fast for a short distance . you better run down hill ,they got short frontlegs and they must go kind of sideways down the hill. Fast enough to catch the slowest person in your hiking party. Faster than you ... and you better hope you can run faster than the friend your with (climbing trees doesn't work)! They have been clocked at speeds up to 35 mph. Well im bout to go race one right quick.
