This page provides tips about your traction while bikejoring.
Your dogs have much better traction than you do.
Beware going downhill on curvy roads when the pavement is icy or wet.
Your dogs, especially if they are sled dogs, have superb traction in this situation, you don't. If it is cold out and they are going downhill your dogs will tend to run fast.
If you are going downhill and the road has hairpin curves, thedogs will really start to have fun, but you won't.
If you wear boots you can use them as outriggers when turning in icy or wet conditions. If you do put your foot down to touch the ground make very sure it is farther out from your bike than the pedal. You can break your ankle or leg or worse if your foot catches on something and the pedal rides over it. In any case, your brakes will not be particularly effective going downhill on icy or wet pavement. You will likely take a spill.
It is better to evaluate your traction and select an appropriate route. Know your routes and rate them for ice and wet pavement. Think through the whole route before you run it.
Once your dogs start to pick up speed, it is too late to fix the problem. If you are on a new route or can't remember, stop your team before they enter any section that might be a problem. Eyeball any section that may be hazardous while your team is stopped. If you must do a section that is hazardous try to walk your team through it if possible. You should know how to walk your dogs when they are hooked to the bike. I grab my “spark plug” dog and make her walk behind the team with me. That gives me more control.
Plan and look before you leap.
