An average walking speed is 3 miles/hour. Our Wheel Dog Title requires you to log 10 miles. So, at a walking pace it would take 3.3 hours to complete. You don't have to complete the miles in one run. But to log a run it must be a minimum length of 1 mile.
If you're just starting, a 3 mile/hour pace is probably a good expectation. You're dog likely isn't pulling consistently yet, so it'll be a little slower as you move them past distractions, and encourage them to keep pulling.
A sprint racing team (made up of 4 or more dogs) might clock in at a blazing 15 miles/hour, but don't expect that of a single dog at the beginning...or maybe ever depending on your dog.
Malamutes and draft breeds may average around 5-9 miles/hour, but don't tend to like going faster than that. Smaller and older dogs might be around that same pace.
Our Wheel Dog Bronze through Platinum Titles require 25 miles logged to earn each title, it would take you 8.3 hours (at a walking pace) to complete each Title level. These early Titles could easily be accomplished in your first month if you only walked a half hour a day.
We hope that gives you an idea of how long it might take to start racking up the accomplishments.
