Integrate gpx track with osm in my site

Hi,
I would like to integrate an OSM map on my site that shows a certain GPS track in the .gpx format. Is that possible?
The page is http://itinerariacavallo.altervista.org/bandita_map.html
Thanks

Yes:

Also see http://leafletjs.com

it has a plug-in dealing with GPX file as a layer.
