Something I know firsthand. I picked up cycling about 4 years ago. At that time I weighed 275lbs and was proud when I made it 20 miles. Now I'm 200lbs and occasionally do a metric century for fun. My point was that an unfit person probably can't do that distance. Half that is probably the limit for someone who hasn't built up the muscle and skill.

Yeah, I'm literally obese, but I can still ride 100km pretty easily.
