One thing that kept annoying me during long rides was how useless normal weather forecasts become once your route is 100–300 km long.

The weather at the start point tells you almost nothing about:
- the climb 3 hours later
- the descent after sunset
- headwinds halfway through the ride
- rain arriving in the mountains

So I built a small web app for cyclists that maps weather directly onto a GPX or route.

You upload a route (or paste a link), choose your start time and average speed, and it shows:
- temperature changes
- wind direction/speed
- rain probability
- conditions hour by hour along the ride

I originally built it for long-distance rides and mountain routes, but people have started using it for ultras, bikepacking and training rides too.

Would love feedback from people here who do long rides or care too much about weather planning 🙂
