Import a GPX file: OnTrace places water, huts and supplies along your route, each with its kilometer. Then share the trace to prepare it as a team.
For now, OnTrace only works in mainland France and Corsica.
Hover or tap the profile to read the altitude and the distance to the next water. Tick the places to show: as in the app, the longest stretch without water is computed from the water points shown.
Longest stretch without water: 26 kilometers, from kilometer 97 to kilometer 123.
24 types of places, grouped as in the app, and camping zones. Tick what matters before you search: the rest stays one click away once the results are shown.
Zones drawn on the map, with their calendar. Where nothing is drawn, nobody knows.
Parks and nature reserves, and what the rules forbid there. Without a zone, nobody knows either.
Each feature answers a question you ask yourself when preparing a race or a trek.
Each place shows its exact kilometer along the route. Sort the list in race order, or by distance from the trace.
Spotted at a glance, dashed orange on the map and on the profile. You know where to refill before you leave.
Elevation gain and loss, lowest and highest altitude, with the water points marked all along the route.
The essentials are preselected, and remembered from one visit to the next. Hide the surroundings of the start and finish, where towns crowd the map. Nearby markers group themselves.
Zones drawn on the map show where camping is allowed, tolerated, restricted or forbidden, and where parks and nature reserves begin. Each has its calendar: hover to read it, open it to pick a date. On your trace, a tab lists the ones you cross, with the kilometer and the period, and warns you of any ban. You can also draw your own freehand, for everyone or just for you.
Stops and stations along the route are places like any other. Open one: its lines show in color, with the next departures and real time when the network provides it. Timetables, regional coaches included, are only fetched at that moment.
Anyone can report the state of a place: flowing or dry, open, closed or temporarily closed, passable or not, with the date seen and a public note. The confidence level takes it into account, and a water point reported dry leaves the dry stretch calculation at once.
The photo of the place if OpenStreetMap has one, otherwise the nearest one on Wikimedia Commons. Its GPS coordinates to copy, and a direct link to Google Maps.
Save the trace, send the link: everyone comments on places under their own name and color. The link alone gives read access, you decide who comments and who manages. Find all your traces, created or joined, in “My traces”.
Export the places shown as GPX waypoints, sorted in route order, with a Garmin icon, category and kilometer.
A real search on a 137 km track: the map, the elevation profile and the list of places follow one another in race order. Hover over the profile to find the spot on the map.
The tap turned off in winter, the spring to check, the hut where the support crew waits: everyone notes it on the place, under their name and color. Everyone prepares the same trace, in the same place, before the start.
After a search, sign in and give it a name: the trace, its radius and its places are kept. You choose your username and your color.
The link opens read only. Invite by username the people who should comment or help manage access.
Notes stay on the place, visible to the whole team, with the name and color of their author.
The link alone opens the trace read only. The owner invites people by username, or among those met on their other traces, and appoints administrators who can do the same. Everyone picks their color, the one their comments carry.
Split the checking of water points and aid stations between volunteers.
Each person scouts a section and notes what they know: dried-up spring, tricky passage, shelter.
Agree together where to meet and where to refuel, kilometer by kilometer.
One link for the whole group, one trace for the week, notes that follow along.
Races, agencies, guides, tourist offices: prepare your routes together, with water, shelters and emergency services on the map. The Pro offer is being built with the first organizers.
Alpine club, sports or leisure association, non-profit? Discover the free Asso offer.
Choose the file and a search radius, from 100 m to 10 km around the trace.
The essentials are already ticked. The server fetches everything, but only sends you your selection. The rest shows in one click.
The list follows race order. The map, the profile and the dry stretch read at a glance.
Send the link to your team to prepare the trace together, or export the points to your watch.
