So there I was planning to go for 7k this morning, as my last long run was 6.25 or 6.75 depending which app you looked at, but erring on the side of caution, as you do, i thought 7k would be a good one to aim for.
First thing that went wrong was I couldn’t hear the app voice so kept stopping to wiggle the lead or pause and resume, all to no avail. So plodded on in silence. Strava was clocking the distance right from the start, which it often doesn’t until I get out of the town centre, but today was a good signal for a change. Couldn’t see what mapmyrun was doing as haven’t sussed much on that one yet, but I think I set it going.
I had planned where to go on the basis of the 6.25 clocked by Strava last time, and I have a loop I can add if not quite enough when I’m nearly home. When I got to that point, Strava said I had done about 5.8 so I started the loop for an extra k. Then my phone told me it was low on battery power and I was petrified I would loose the run if it shut down altogether, so went into low battery mode, which meant I let the screen blank out.
When I finished the loop, the screen (still working thank goodness) showed me 7k so I headed home feeling smug. When I got home (and charged the phone, no data lost 😊 but headphones appear to be dead 😩) and looked at Mapmyrun, it said I had done 8.1k but Strava said 7.1
So now I am totally confused. The picture of the route is identical in both apps but the distance a whole k out. I know it was half a k different on my 6.25/6.75 run last week, but a whole kilometer? How can that be?
So I reckon I’m up to 8k now, (being a glass half full sort of person) or should I really take the average of the two, at 7.5k
Any ideas why it should be so different? What am I doing wrong?
