Strava inaccuracy
Today I rode 46.9 mi as measured by by magnet based speedometer (wired). Rode really fast, and checked Strava at home (I recorded it on my smartphone during the ride). Strava says the ride was 28.6 mi. Needless to say, i'm not pleased. Missing 18 mi?? Basically it didn't record my ride home. There were no tall buildings or mountains to obstruct gps reception, and in the past I have felt Strava was reasonably accurate. Has anyone else had this problem, and is there a way to fix it? Was thinking about going to a GPS based speedometer like the Garmin Edge 520. Now i'm not so sure.
