I send everything to Strava and in that forum i can edit a ride and trim off the end if i forgot to turn it off when i got back to my car. While i would love to have 70 mph times on my bike, it just isn't accurate. It is really easy to do in Strava but the only thing i have seen here is export the data and manually edit it in a text editor. That can't be it, with features like top speed for 40K etc, i sure would like to have them available, can't something be done to make this as easy as it is to do in Strava?
