It really isn't too much harder than on a geared bike. It's tougher yes but not by the orders of magnitude you might think.
Distance riding is doable, even pleasant if you train properly and work up to it. 55 year old randonneurs do 1200 km in 72 hours, so there's no reason why a young **** like you or me can't do 160, fixed or not. Start by training for a metric. That's just what you did plus 40 km/ 25 miles more. You'll be really surprised how fast your "range" increases even under haphazard training. Regular rides on weekends with gently increasing distances and or speeds will prepare you, no sweat.
The long distance forum has lots of great advice on century training.
