I think bikejoring as a competitive sport is ridiculous. The profound mechanical advantage of the bicycle almost negates the power of the dogs. I can put a Chihuahua in a basket on my bike and win bikejor races simply by riding as fast as I can. I would not have to brake on the descents to check the speed of my dogs if the course was rough. I would be able to bomb downhills and at the finish, let out the Chihuahua to cross the line in front so I don't break the rules. Unless the course is all climbing then a team of good dogs will just slow me down. Bikejoring is great for training dogs but if you are allowed to pedal then the sport becomes a lot less sporting. When I train dogs on a bike I pedal as little as possible because my objective is to work my team.
I have a long history with bicycles. I raced road bikes during the late 1970s until the mid 1980s. I then changed my emphasis to mountain bikes and raced mountain bikes into the early 1990s. When I took up skijoring and bikejoring I phased out the bike racing in my life. I feel equally comfortable on a bike or a scooter when running dogs.
The popularity of bikejoring races is growing. The reason is that many people already own a bike and use it to train dogs. Far fewer people own a scooter. I would like for more competitive dog drivers invest in a scooter. I would like all race giving organisations to emphasize the scooter class as the pro class for one or two dogs and make the bikejoring class a novice class. Racing dogs should be all about the dogs and not the rig. Pedaling a bike while racing is eqivilant to using a motor on your ATV when training a team of dogs.
