I had to back off that and instead do other games (ie, wandrer.earth gives you points for "new miles") because I got a bit too competitive and borderline dangerous.

Besides, I got records and fastest times when e.g. wind was at my back or the lights all went my way - so I knew it wasn't just my effort & just happenstance.

I still use Strava - mostly as a personal blog of my efforts & take a picture of wildlife or crazy videos to share with others sometimes.
