If you can run 20 mph for 20 miles...1 hour, I will give you all the medals from Rio (that won't get used anyway).

The average human pace is between 3-5 miles in an hour jogging. All out running killed the first marathoner (who was delivering battle information to the Greeks or something)...he made it and collapsed and died.

The reason that you could do 20 mph on a bike is GEARING. Short, up and down strokes to a round driver and at least 1.5 to 1 ratio or greater makes a bike fast, along with quality hubs and bearings.

If Strava has outed you, you probably deserved it. Obey the rules of the trail and be safe towards all other users. High speeds also equal greater trail damage, as do certain tire types. Preservation of the trail is paramount as the manmade damage contributes to excessive erosion and instability, ruining the trail for all. When a path is muddy it is often closed as well.

This is something that has been gone over in the foothills areas of Boise a few times.
