Strava Yargo distance

Postby KevinH » Sat Jun 01, 2013 5:25 pm

I ride a lap around Yargo most Saturdays, including Monster Mile and 3-Step. Strava has this distance at 11.1 miles consistently.

So today, I gave two laps a try. I skipped Monster Mile on the second lap so I would expect the second lap to be around 9.5 or 10 miles for a total of about 20-21 miles for both laps. Strava came in at 18.7.

Is Monster Mile really 3.5 miles or did Strava not properly calculate the second lap?

My time for the first lap was 1:20 and the overall ride was 2:33. That puts my second lap time at 1:13 which seems about right...for a 10 mile lap. NOT for a 7.5 mile lap!

I use an Android phone for Strava and it is off about 1/4 mile per mile that I ride. I rode yesterday and went 19.9 miles and Strava only showed 15.5

My Garmin is also off by about 1/2 mile at Ft. Yargo. Any bike computer I use consistently registers it longer than the Garmin.

try mytracks. i run it and strava at the same time and it's usually more correct than strava...
clearly it's entirely too technical...

Thanks all.

I'm not really worried about strava's accuracy when it comes to distance. I'm more questioning why two laps on the same course showed such different results. In other words, if the lap is exactly 11 miles but Strava calculates it at 10 miles, I'm fine with that. But it should then calculate two laps at 20 miles. Wrong is OK if it's consistent.

Looking back at my ride, it shows each lap as a segment but fails to total it correctly:

Yargo CCW w/ Monster Mile: 11.9 miles
Yargo CCW w/o Monster Mile: 10.8 miles
Total Ride: 18.7 miles

The GPS receiver in your phone doesn't update fast enough. Its probably a 10htz receiver where the higher end gps units are closer to 60htz. As much as fort yargo doubles back on itself I'm not surprised it misses a lot of it.
