I think it is awesome if you ride your bike with your Yorkie! I would do it if I could ride a bike. I can jog, but my knee can take the motion of riding a bike and although I have tried I could not go around the block, I get about halfway around the block and the pain in my left knee is so bad I have to get off the bike and walk it home.
I would love to jog with my Yorkie if that was possible, but I am not sure he would like the movement of my jogging in any type of carrier. I would gladly take him to do a 5K like that, but I don't see it happening.
I am a very slow runner. I figure that jogging slow is better than sitting on the couch though
