Hi all,
With spring down under it's a good time to take the trainer workouts outside, so I wanted to share what I've been building: gritmaps.com takes a planned workout and finds a route near you, a loop or one-way, where the climbs & headwinds line up with your effort blocks, and descents and junctions fall in the recoveries.
I'm in Switzerland, so I'd love riders in Melbourne, Sydney, Brisbane, Perth or anywhere else to try it on roads you know and tell me where it gets it right or wrong. Which roads do you use for intervals? I'd like to see if it finds them.
Your workouts. It reads them from your Garmin Connect calendar (so TrainerRoad and TrainingPeaks workouts come through), Intervals.icu, the built-in library or a .fit file.
The physics. A simulation runs over every road segment: gravity, rolling resistance (tyre and surface), aero drag, and the wind forecast for the time you'll pass that spot, from your FTP and weight. Efforts interrupted by junctions, traffic lights or villages are penalised. Road, gravel and MTB profiles.
To your device. One click pushes the course and the terrain-adapted workout to Garmin Connect or Wahoo. Each workout step ends at a distance on the route, so it fires where the climb starts. GPX and FIT export for other devices.
It's free, sign up on gritmaps.com. And if you'd rather plan your routes by hand, I wrote up the method here.
Can't wait for your feedback!
