Are thieves actually scrolling through Strava finding local segments, tracing back through rides and searching for users or is it a bit of internet scaremongering/urban myth?
Start/finish your rides at a “non-home” location – ideally somewhere pretty open like a junction or town centre where it’s impossible to pinpoint one house or one road.
Don’t Strava your commute, it sets up a regular pattern of where you’ll be at what time.
Don’t publish the name of your bike – call it “road bike” or something instead of “my amazing £7000 Cervelo”
Don’t have all your mates starting their rides from outside your house.
Similar to any internet activity surely, just keep at least some degree of privacy in terms of who you allow to follow you, who can see your pictures etc.
