You can do it on a bike or in a car, or on some apps (not sure about map my run) you can "Draw" the route on a map and upload it.

Yes, it's reasonably straightforward to create a fake GPS track.

Why one would want to do that is a different matter. A 4:37 50k is hardly the stuff of dreams.

Join him on his next 50k run and you'll soon find out.

First thought was bike or car, but riding a bike at a really slow speed? I normally run at about 12km/h bike is upwards of 25km/h. I'd find it hard to cycle at that slow a pace.
I noticed there's no calories burnt, surely the app would have calculated that?

Just out of curiosity and hopefully it's ok to ask but how do you trick a GPS? If it's not, mods feel free to delete the that question.

Actually tricking a GPS (i.e. having false signals arriving into the device) would be pretty difficult. However, modifying a GPS file that's already created (or creating one from scratch) is trivial. A GPS file is essentially just a long list of lines with 3 items on each line: Latitude, longitude and time. E.g.:

• At 12:00:00, location was (53.344103999999990000,-6.267493699999932000)
• At 12:00:01, location was (53.344103999999991000,-6.267493699999932000)
• At 12:00:02, location was (53.344103999999992000,-6.267493699999932000)
• etc. etc.

Three's nothing illegal about that question.

On a basic level those files just note a location and timestamp (plus any additional information like HR or power or anything else, but that's beside the point).

GPX is an xml format, it is human readable and rather trivial in its structure. You can use any text editor to create or change one.

You can either handcraft a file with loads of waypoints in there or you can use any one of dozens of existing tools that help you with that. It's fiddly but technically it's very straightforward.

Again, why anyone would want to do that is a different matter. I sure would prefer to run 50k than to fiddle around with a file until it looks believable.


P.S. Editing gps tracks can actually be handy at certain times, e.g. if you forgot to press the stop button after a race and desperately want your "real" race data.

I use a Polar RCX5, the GPS can take a few minutes to get a signal or fix, normally it's not a problem but hanging around in this weather waiting for it; that could actually be handy. Thanks I was curious how you'd manage to change it. I might give it a try and see what happens.

Not that I condone this sort of thing, but here's a website that will do it.
