Anyone any views on the accuracy of mapmyrun.com? I have my doubts. Sometimes it makes me look like a superathlete, othertimes I think it underestimates distances.

I would say its pretty accurate if u map ur run in detail. Hve found it pretty close to my garmin... but u do need to go into detail..

I've only used it a couple of times but find it's way off in comparison to my garmin.

How far off, 10%? I presume the Garmin is US military style accurate?

i mapped 2 runs there that I know the distance of, and it seems pretty accuarate. Certainly not 10% out, or anything close.

It's pretty accurate if you use it precisely - i.e. Following bends in roads etc. Difficulty is that it does all its measuring in straight lines. Try Gmaps Pedometer which uses Google Maps and calculates all the road twists and turns for you.

I find it accurate aswell but you have to magnify in close to make sure you are staying on track.

mitresize5

pretty much spot on with my Garmin as well - but as the others say you have to get right in close

That explains all the 'friendly fire' losses!! :D:D

I use MMR, in Satellite mode, to check out courses before measuring. The normal, street view, mode is u/s - it can be literally metres away from the real road and 'straightens' bends and curves.

As regards training runs, what does it matter if you are running 9.75/10.05/10.25/whatever for 10 miles, as long as your intended effort target is met. Too many people get hung up on being precise in their training runs.

At the end of the day, Jones counter is the only one that matters....and I've NEVER measured one of my training routes. MMR/Garmin is adequate and, even then, Garmin varies slightly every run, but, like I said earlier...I couldn't give a fiddlers about the variation.:)

I've mapped my run home, and according to the mile markers it gives, I always run my second, uphill mile faster than my first mile. I doubt it.

But yeah, it doesn't really matter even if it is off by 10%. It's just a training run...

a148pro

well it does matter if you're not training for anything, i.e. if you're not going to ultimatley race a known distance, which is the position I'm in. I'm just running for the crack / fitness, and would like to know how far I've run. but I ain't payin to find out...

Find it pretty accurate, but getting a Forerunner (305 or 405) for the birthday so hopefully will get better readings

Found it fairly accurate, defo not out by 10% though. Altough my last run definately felt like MORE than runnigmap said it was. :eek::)

Last week I found that runnigmap.com wolud keep throwing a server errror everytime I tried to measure a route (although I haven't registered to it, maybe thats why)

petermijackson

Yeah I find it fairly accurate as accurate as the Garmin maps

I used Mapmyrun earlier this week to map a route in the Wicklow Mountains and found the elevation details to be way off. For instance, it had the steepest slope at the 5-mile mark, which was actually a relatively flat stretch. The steep slope was closer to the 7 mile mark.
Of course, this won't matter for most of us.

I have tended to measure my runs by manually using the 'measure path' tool in Google Earth. I feel its more accurate for measuring long distances on the narrow twisty country roads that Im usually on.

As other posters have said I also find it accurate - but only if you zoom right in. If you don't you can't expect it to be right.
