How long would a 3 hour walk on a bike take?

About an hour.

What????? Good one. hee, hee!! That’s like asking; how long would a 3 hour bike ride take on a walk?. However long it takes you…

Average brisk walking pace on level ground is 4mph for a fit walker, so a three hour walk with no resting stops is about 12 miles. . Putting similar effort into riding a cheap mass produced sports cycle on level roads gives about 18 miles per hour, and that would enable you to cover the 12 mile distance in 40 minutes. Or on a cheap mountain bike around 48 minutes at an average speed of 15mph. . The same reasonably fit regular cyclist, if used to cycling a good quality road racing bicycle would cover the distance in about 30 minutes at an average speed of around 24 mph. .

. Change the route to rough track mountainous terrain and the walker would only cover about 2 miles per hour giving a total distance of 6 miles. A cyclist on a sports bike or racing bike would get off and walk, while pushing the bike, and would be slowed down by the bike, taking more like 4 hours to cover the distance. The cyclist on a mountain bike / all-terrain bike would probably cover it in about 45 minutes, but a lot would depend on just how rough the terrain happened to be and how big a proportion was downhill. .
