hmm, my post didn't get added.
You've shown a link for sport tracker for Symbian and two PDA's that are running Windows mobile or CE, which clearly aren't compatible.
Like I said you need a device running Symbian, Windows, iOS or Android.
If you can find someone who has written a sport tracker app for CE or WinMo you might as well by an old HTC Titan or such like as they are less than £50 and have built in GPS, then there is something like the Nokia 5800 that's also less than £50 and that will work with the sport tracker app you posted.
I had a WinMo device (An Orange SPV C550, followed by an E650) and SIRFstar bluetooth GPS running Tomtom back in 2005. I had to hack tomtom onto the device because of dodgy comport and screen configs of the SPV's, but the OP wanted a sport tracker and I would suspect that unless the old version of Endomundo works with those old versions of CE it wont work.
This Nokia 5800 is only £36.50 [url]http://www.ebay.co.uk/itm/Nokia-XpressMusic-5800-Chrome-Edition-Smartphone-TMobile-/360508594297?pt=UK_Mobile_Phones&hash=item53effc9879[url] and works with Endomundo (wife used it on hers) and also probably that sport tracker too.
