Re: "key features really well", they're not even doing this.

My normal morning jog goes under a large bridge. This often confuses my phone's GPS, leading it to return a spurious point or two a kilometer away. Strava is completely incapable of detecting these spikes (accelerating to 200 km/h when running is normal right?) and offers no way to edit them out afterwards, meaning all my speed and distance records, progression charts etc are ruined by junk data.

What phone are you using? This surprises me because most phones are using some sort of sensor fusion to deal with this exact issue.
