Bestrida, swedish translation "to challenge", is a Strava.com segment based application that allows you to challenge your friends to running and cycling segments. With the chaotic schedules many of us have, it’s hard to carve out time to actually meet up with a friend and go for a run or ride. Your friends no longer have an excuse to keep dodging your challenges just because you're an Ironman and they’re a weekend warrior. Select an opponent, segment, and completion date to get started. You can challenge your friends using the app, anytime, anywhere.
