Turn a long trail into an editable multi-day plan. Upload a GPX and split it into balanced daily stages — each with distance, ascent, estimated time, and its own downloadable GPX. Built for hut-to-hut hikes, thru-hikes, and fastpacking. Everything runs in your browser.

Upload a GPX for any long trail — a national trail, a hut-to-hut route, a thru-hike, or a custom Planner route — and choose how many days you want. The builder splits the track into balanced stages by estimated time rather than raw distance, so a day with a big climb is not made unfairly long. Each stage shows its distance, ascent, descent, and a Naismith-style time estimate, and you can download a GPX for any day or the whole trip as one file with a track per day.
Your GPX is parsed and split entirely in your browser. Nothing is uploaded.
It balances the days by estimated time, not just distance — so a big-climb day is not made unfairly long. Pick the number of days and each stage gets a roughly equal effort.
A Naismith-style model: your flat hiking speed plus a climbing rate (defaults ~4.5 km/h and 400 m ascent/hour). It is a planning estimate — adjust for pack weight, terrain, and fitness.
Yes. Download any single day, or download the whole itinerary as one GPX with a separate named track per day, ready for your watch or phone.
No. The file is parsed and split entirely in your browser. Nothing is sent to a server.
