Another option is to use a web page. For example I do a custom page for the Baker to Vegas run each year. It not only shows positions but figures out the leg on which each team is, and the position in that leg, and sorts the list. At one point this was the largest APRS even, though the use of trackers has fallen off in the last few years, presumably do to use of smart phone trackers which are easier for non-technical teams to implement.

Boring without someone on the course! The maps are deliberately simple, in this case an APRSdos map, so as to make the positions stand out. 

I'm not anxious to put this kind of effort into a new event, but findU has features that let you put up a map to suit your needs and create your own pages. With geo files you can create any sort of map you would like to put under the tracked position, list multiple callsigns to put on the map (or if you on't care about non-event station showing up use 'call=*' to see everything.

The advantage of this approach is you can email a URL and everyone with a smartphone can see it, no need to install and configure an app. I'm sure aprs.fi has similar features.

It's main deficiency is that it depends on Google Maps online for the mapping display.  there is (at least for now) no provision for off-line maps cached locally.

You can download and store locally any part of the world.  The download dialog looks like a directory tree where you drill down by continent, then country, then state/province, major metro area etc.  I have ALL of the US and Canada at street level parked in about 1.7GB on my iPad and iPod Touch.

For these, I use the Dual GPS150 external Bluetooth GPS.   This GPS is a very versatile device that can be switched between Apple's proprietary GPS format for i-Gadgets, and standard NMEA for Windows devices.
