Teaching husky to pull?

I recently got a new husky from an animal shelter where I live. He's about a year old, and frankly, I'm not much of a runner. However, I do skate. So, I took him out on and had him pull me on my skateboard for exercise and he did really well. The only problem I had was that he's used to walking with me, where he goes my pace. So, when he is pulling me, he goes however fast I'm going. Which means that to start, I have to start going decently fast on my skateboard, and even then he stays at a consistent jogging rate. It also means that when I stop, he stops. So, I want to know how I can let him know that its okay to run as fast as he wants and doesn't have to stop till I give him the command.
