Milemark

Stop guessing how much of the drive is left.

Drag your dot along the route and see what is behind you and what is ahead — in miles and in driving hours. Virginia to Anchorage is 4,239 mi and 85 hours, and knowing you are 62% done is the number you actually want.

Milemark

Trip details

Trips, routes, charger sweeps, the passport and your preferences. Tick the box to carry the Tessie token across too — the file then holds a credential that can drive your car, so mind where it lands.

Charging and driving after this date and within 25 miles of the route. Saved with the trip.

What you actually drove each day, from the car's own trip log. Press Refresh on Energy Used to pull it. With a plan committed, each day is measured against it.

Chargers ahead

The itinerary below covers the whole trip from the origin — Day 1 is your first day of driving, and the day you are currently on is highlighted. Rest days are added on top. Charging % pads the driving time to cover plug-in stops; 15% is a reasonable default for a Tesla on interstates. Saved with the trip.

Day by day

Log an odometer reading

Enter the readings straight off the dash, not the miles for that day. The first one is the baseline — it zeroes the count, and only what you drive after it counts toward this trip. Every later reading contributes the difference from the one before it.

Tesla’s 2026 competition counts distinct Supercharger sites, not sessions or kilowatt-hours. Sites come from the supercharge.info register; visits come from your own charge history in Tessie, matched to a site when the car parked within 150m of it.

The competition’s Longest Trip category counts the longest run of distinct Supercharger sites where each new one is reached within 24 hours of the previous session’s start. A session at a site already in the run holds the clock open without lengthening the run.

Open Charge Map key

Optional. Without a key Milemark uses OpenStreetMap's Overpass API, which is free but slow — a full sweep of a 4,000-mile route takes minutes and sometimes times out. A free key from Open Charge Map makes it a single fast request. Stored only in this browser.

Connect your Tesla

Uses Tessie, not Tesla's Fleet API — no OAuth, no backend. These are the same values as TESSIE_TOKEN and TESLA_VIN in grc-cc. They are stored only in this browser.
