Walking Detroit with FOG
Detroit is flat, radial and much bigger than its population suggests. Filling it in rewards patience and a plan.
Spokes over a grid
Detroit was replanned after the 1805 fire on a hub and spoke idea, and enough of it survived that the city still radiates. Woodward, Michigan, Gratiot, Grand River and Jefferson all run out from the riverfront near Campus Martius, and an ordinary square grid fills the wedges between them. It is flat from the river all the way to Eight Mile, with nothing that counts as a hill.
The spokes are long. Woodward goes from the water through Midtown, past the museums, up through New Center and keeps going into the suburbs. Walking one gives you a straight bright line across the map that is visible at a zoom level where nothing else is.
The riverfront afternoon
Start on the RiverWalk near Milliken State Park and walk west along the water past the marina toward Hart Plaza and the Renaissance Center. Double back and pick up the Dequindre Cut, the old rail line sunk below street level, and follow it north to Eastern Market. From the market sheds it is a straight walk up to Midtown and Woodward. Call it seven or eight kilometres, most of it on dedicated path.
Corktown is the other obvious half day. Michigan Avenue out past Michigan Central Station, then the residential streets around Bagley and Trumbull, which are old, small in scale and quick to light up.
The honest part
Detroit covers about 360 square kilometres for a population that would fit comfortably in a third of it. Between the spokes there are whole districts of wide streets, big gaps and long blocks with very little on them. Walking those is not unpleasant, but it is slow, and the city percent will not reward you the way a dense old core does.
What works is treating Detroit as a set of separate walkable islands. Downtown, Midtown, Corktown, Eastern Market, West Village, Belle Isle. Light each one properly, then use the avenues to connect them. Your map ends up looking like a wheel, which is exactly what the city is.
Winter is real
Detroit winters are cold, grey and long, and lake weather can keep the sky shut for weeks. Snow left on an unshovelled stretch of sidewalk will end a route early. Spring and autumn are the good seasons, and summer along the river is as good as walking gets in the Midwest.
If you walk through the winter anyway, keep to the stretches that get cleared: the RiverWalk, the Dequindre Cut, the main Midtown streets. Those are also the ones you will repeat most, so it is worth pushing one block off them each time to add something new to the map.
What the app is doing
The world starts under fog. Only streets you have physically walked are revealed, and they stay revealed permanently. Walking, running and riding all count, and background exploring keeps it recording with the app closed and the screen off.
Nothing is uploaded. No account, no sign-up, no cloud, no analytics, no ads, no tracking, and the map never leaves your phone. Free to explore. One purchase of USD 5.99 unlocks unlimited ranks, every character and history import, which reads Google Timeline exports and GPX files. No subscription.
Questions people actually ask
Is Detroit realistic to fill in on foot?
Not completely. The city is around 360 square kilometres of mostly low density. Walking the core districts and the main avenues is realistic. The wedges between the spokes are a long project.
Does riding count, or only walking?
Walking, running and riding all reveal the map, anywhere on Earth.
Can I bring in routes I recorded years ago?
Yes, through history import, which reads Google Timeline exports and GPX files. It is part of the USD 5.99 unlock.
Does FOG need a signal or an account?
There is no account and no sign-up, and nothing goes to a cloud. Everything stays on the phone and you can export it.
