GPX

GPX is a free cycling route planner for the United Kingdom that supports road and gravel riding. Users can build routes point by point on a map, generate round-trip loops, or compare A-to-B alternatives. The planner uses open data such as police-reported collisions, Department for Transport traffic counts, mapped cycle infrastructure and OpenStreetMap surface tags to score candidate routes based on distance, climbing, busy roads and surface quality.

The website says the planner is surface-aware, allowing users to choose riding modes like quiet-lane road riding, fast tarmac, mixed terrain or gravel-priority. Every candidate route is scored on open data including reported collisions and traffic counts. The in-browser fused A* engine runs on your own device and is labelled 'Ours' when shown next to mainstream alternatives.

The benchmark page explains that turn burden is treated as an exposure proxy because a right turn crosses oncoming traffic while a left turn does not in the UK. This asymmetry is measured alongside crash exposure and traffic stress to judge how unpleasant a ride might be at junctions. The methodology sets out a metric suite covering crash exposure, traffic stress, turn burden, efficiency and comfort.

Users can plan a route by tapping the map to add start and next points, then drag points to adjust them. They can generate a round trip that comes back as an actual loop or compare A-to-B alternatives side by side. Planned routes can be exported as standard GPX files compatible with bike computers like Wahoo.

The website states there is no subscription, no advertising and no account required to plan a route. An optional Google sign-in syncs saved routes across devices, but getting started, saving and bike computer help are available without logging in. The planner is free to use for all riders.

The benchmark results page mentions testing against BRouter, OSRM and Valhalla over a fixed set of UK route requests. The results update whenever the benchmark is re-run, and the methodology and limitations are set out in full on the website. The abstract notes the benchmark covers 527 cases as of September 2026.

The map includes overlays for public bridleways and byways, the National Cycle Network, traffic volumes, collision context and LiDAR-refined gradients across England. Users can zoom in to see bridleways, traffic counts and collision dots directly on the map interface.

The planner allows users to draw their own route by finding their area and adding points on the map. After reviewing the route, users can save it and download the GPX file for their bike computer. No account is needed to perform these actions.

The website describes the service as 'British roads. Bigger days' and aims to find quiet lanes, gravel tracks and a different way home. It is designed for riders who want to make the ride their own, whether for a day out or exploring established UK trails.

The benchmark abstract states that the metric suite covers crash exposure, traffic stress, turn burden, efficiency and comfort. These metrics are used to run the router against other engines over a fixed set of UK route requests, including cases drawn from ridden routes and synthetic stress tests.

The website mentions that the in-browser fused A* engine runs on your own device rather than on a central server. This means the routing calculation happens locally when you use the 'Ours' route option.

The benchmark page notes that routes are map-matched onto one shared road graph so that no engine is scored on its own account of itself. This ensures a fair comparison across all routing engines tested.

The website states that the planner supports both road and gravel riding modes. Users can switch between these modes to see how the route scoring changes based on the preferred surface type.
