Home from a 75 mile ride out and around a reservoir 40 miles west of Portland.  LSD.  Stopped once to pee at mile 15, then only put my foot down at lights (none in the middle 60 miles) and for a couple of major street crossings.  43 x 17 on my good ti fixie,  The route is not flat but not hilly until the 8 mile loop around the reservoir where the dam is the only flat road.

I've done this before both geared and fixed.  This was the lightest, fasted fixie, 8 pounds and 40% lighter then the first fixie I did this on.  Also a slightly lower gear.  Still, VERY real!  I'm feeling it despite never going hard, never digging deep for wind or grunt strength.

The great part about riding fix gears is the ability to get real quality rides that set a really good base for the future in limited time and without requiring great discipline or lots of electronics.
