Heatmap user frequency on trails
- 
 I wonder how many times a path or trail needs to be used before it starts to show up on a heatmap? There’s a segment of my route to work (running) that has no trace of “heat” on the running heatmap. Does anyone know how many times a route needs to be used before it starts to show up as a faint line? 10 times, or hundreds of times?

 I suppose you used the trail map. I think heatmaps are updated once per month
