Windline turns your GPX routes into one live link. Every rider sees the headwind, gusts, rain and heat for the exact hour the group reaches each stretch of road, on a multi-day tour, a stage race or the Saturday club ride.
Weather apps forecast one place at one time. A tour covers 200 km a day, through different weather, at different hours. The wind at the start tells you nothing about the climb at 11.
Load the routes once. From then on, every time someone taps a day, they get the newest forecast, timed to their ride.
Upload the GPX file for each stage. Windline reads the distance, climbing and direction of every stretch of road.
Date, start time, riding speed and stops. We work out when the group reaches each part of the route, slower on the climbs.
Paste it into the group chat. Each day gets a live Good, Fair or Tough rating, and one tap opens the full map.
Pick what you are running. Windline sets the page up the way your riders use it.
Every day of the tour on one page, each rated Good, Fair or Tough, timed to the group's pace with climbs and stops built in.
Set a planned speed for each stage. Every rider shifts it faster or slower to see the wind for their own time on the road.
One link that never changes. It always shows the next four rides on your route, and each rider sets their own pace.
Cold fronts due over your days, an overview map of the whole event, and a branded image of any day to post on Instagram or Facebook.
San Francisco to Solvang along California’s coast, 628 km, always starting two days from today. Each day below was just rated in your browser from the latest Apple Weather forecast, exactly as your riders would see it.
Connect Strava once. After every ride, Windline adds what the wind did to it to the ride’s description: where it was against you, where it pushed you home, the gusts and the temperature, at the times you actually rode. Your followers see it too.

Tap a day and the whole stage opens on the map. These are real screens from the 116 km Big Sur stage, into a headwind.

Each arrow is the wind where the group will be at that hour. Red is in your face, amber is from the side, green is at your back.

Tap wind, temperature or rain for a chart through the day. See when the wind builds and the gusts peak, and plan the regroup before then.

“Headwind 10, gusts 28, at 06:47.” Every few kilometres, the wind and what it means for the bunch.
The forecast behind Apple’s Weather app, read hour by hour at every stretch of your route, anywhere in the world.
Wind is blended between hourly readings to the moment the group reaches each stretch, not rounded to the hour.
Each day’s rating works out the effort the wind costs or saves at your pace, then side gusts, rain, heat and cold. A tailwind never counts against you.
Tailwind: about 37% less effortForecasts refresh through the day, up to 10 days ahead, and every rider sees the same forecast on every page.
You plan the start times, the regroups and the support vehicles. Windline gives you the wind for every one of those decisions, and gives your riders one place to look.
