I have at home my GPS Results to analyze my GPS tracks, but here on the move at Burrum, I have none.
If there is available online any GSP analyzing software to review GSP record from the day and find out :
where exactly the spot for best 2 s was,
where I did my best 5 x 10

where was nautical mile best time on this 3 km long run?

Things like that if available online ( and free) for analyzing tracks downloaded KA72 could be very useful.

If there is any website that could provide this graphical analysis?
