Build the hilliest cycling loop in Luxembourg

Yes. Stiip is a free cycling route planner, you can build hilly loops, find climbs and export GPX files without an account, sign-up or payment, and there are no ads. During busy periods you may wait briefly in a queue while the server builds your routes. A premium tier is planned for supporters and high-mileage riders, with extras like longer routes, but the core route planner stays free.

Stiip is a free cycling route planner and climb finder for road cyclists. Its loop generator is a round-trip route planner: give it a start point and a distance, and it automatically creates several circular routes that begin and end at the same place, routed over the hilliest roads nearby. You pick the loop you like from an elevation-ranked list and export it as a GPX, no dragging a line around a map.

Stiip is built to chase climbing, not just kilometres. For every search it generates many candidate routes over the steepest terrain around you and ranks them by total elevation gain (D+), so the loop you choose packs in as much climbing as possible within your distance. Instead of hoping a route turns out hilly, you start from the hilliest option, perfect for training, chasing D+ or riding the best climbing roads near you.

Type a start town or tap the map, set the distance you want to ride, and Stiip returns a ranked list of the hilliest loops that fit, each with its distance, total D+ and a full elevation profile. Choose the one whose profile suits your legs and export the GPX. Planning a ride around a target amount of climbing takes seconds instead of trial-and-error on a manual route planner.

Open the climb finder, drop a point and pick a search radius, and Stiip scouts the biggest climbs around you from open OpenStreetMap and SRTM elevation data, ranked by gradient and elevation gain. Each climb shows its length, average gradient and total ascent, so you can spot the steepest hills and hardest cols nearby, then build a whole ride around the one you choose.

Yes. The challenge builder plans a point-to-point route from your start to a destination, packing in as much climbing as possible along the way, one big ride to a summit rather than a loop home. It's ideal for a hard day out, a personal-record attempt or bagging a famous col, and every challenge exports as a GPX for your Garmin or Wahoo.

Yes. Every loop, challenge and climb exports as an accurate GPX file you can load onto a Garmin or Wahoo head unit, or import into Strava, Komoot, RideWithGPS and other cycling apps. There's also a one-tap Google Maps link for a quick preview, and no account is needed to download the GPX.

Stiip uses road-bike-friendly routing that keeps you off motorways and favours quieter, paved roads that are pleasant to cycle. A one-tap toggle lets you avoid gravel and unpaved tracks entirely, so a road-bike ride stays on tarmac. It's designed for road cyclists who want real climbing without surprise surfaces or heavy traffic.

Stiip covers all of Luxembourg, the Éislek (Oesling) hills, the Mullerthal and the Moselle valley, as well as neighbouring Belgium, France and Germany. Build hilly loops, plan challenges and find the biggest climbs anywhere in the Grand Duchy, with more regions being added.

No account and no app store are needed, Stiip runs in your browser on phone, tablet or computer, and you can install it as a lightweight web app (PWA) for one-tap access. The core route planner (building loops, finding climbs and exporting GPX) is free and will stay free; a couple of limits apply for now, routes are capped (loops up to 100 km, challenges up to 60 km) and at peak times you may wait briefly in a queue. A premium tier is coming for supporters and hard riders with extras like longer routes.
