fetcheveryone Jun 2014 5:52pm, 4 Jun 2014 14,379 posts	Quote Pin fetcheveryone I've been working on a bit of code today that takes any route, and reduces it to a set of checkpoints, like in this little pic: When you run a route with your GPS, it records hundreds and hundreds of data points along your route - but in terms of describing where you've been, you don't really need that many. And by reducing a route to a small number of pertinent checkpoints, we will hopefully be able to do cool stuff, like race each other from one point to the next. If you have some routes in your routes list: http://www.fetcheveryone.com/routes-private.php you should now see a little 'target' symbol next to each one. That's there so you can take a look at how your routes boil down into checkpoints. It'd be good to iron out any weird bugs now, before I move on and start thinking about the next bit. Cheers Fetch

So after a general run along paths that present themselves to me, Fetch can surprise me by telling me I last ran along that route on such-and-such a date?

Regarding racing each other- for technophobes like me who will create a route manually, then put in an overall time would I get an average time for that point-to-point bit? (Mind you, FetchPoint still isn't working properly for me...)

JohnnyO Jun 2014 7:44pm, 4 Jun 2014 17,690 posts	Quote Pin JohnnyO I like ~~strava~~ it allows me to compare my own performance in speed sessions and gives me a target by comparison with other locals. It doesn't work in a race, becasue I am never going to win anything, but it is entirely possible for me to 'win' a segment on Strava. This sounds like it would do the same, in a way.

Chris - the idea is that I can compare any run that you log against the checkpoints in that local area - so yes, if it matches the list of checkpoints for a specific route, then I should be able to automatically assign that route to your run. This was the original purpose behind my thinking. Routes can be plotted with an enormous number of points - and comparing those against training runs, which also have a massive amount of data points, would be computationally explosive I've not come up with a better way to define a route in simple terms, other than to break it down into a series of relevant points. Of course, from that comes the inevitable idea that you can see who goes the fastest - but we've been doing that for ten years now. Willy waving optional
