All three loops are real output from the US graph — numbers exactly as the router returned them.
The difference
Millions of roads never say what they are made of.
Most planners assume tarmac. We plan with the truth — the road bike goes around, the gravel bike goes through.

SURFACE
No surprise gravel
When in doubt, the road ride goes around — untagged ways included. Gravel and MTB flip that on purpose.

Questions
Answered briefly.
The five that actually decide it. The rest are one page away.
See all questionsWhy not just use Komoot?
Komoot does almost everything — and it is built for every kind of bike. That is exactly why a way with no surface tag counts as rideable there. Here the sport decides: the road loop goes around it, and the gravel loop has its own model that hunts the tracks instead of avoiding them.
How do I know a loop is any good?
You do not have to take our word for it — you can see it. Every loop states how much is tarmac, how much is gravel and how much is untagged, before you ride. Tap any point on the line and it tells you the surface right there.
Which region is covered?
The United States. Colorado is where it is developed and tested first — every example ride on this page is real output from that data. Other countries have a waiting list.
Does it work with my Garmin?
Yes. Export is a GPX file with real elevation — Garmin, Wahoo, Karoo and anything else that imports courses.
Can I cancel any time?
Yes, monthly, one click in your account — access runs to the end of the paid period. And you keep the ten free loops a month afterwards anyway.
