how to compare multiples track records as 'laps'

Hi,

I am running very often e.g twice a week, the same nice path. I am recording it. I end up with multiple records of the same path. I'd like to be able to comapre from o e day to the other to see progress

Is there a way to summarize these records in one unique 'training' where i would see the various days similar to the track feature

It could be the 'lap' feature if

- I could re-start a record

- define the lap as one path i.e starting / ending point

but i find the 'lap' feature does not do it

or any similar feature....

J.
