Tough treks school records across Spain and Portugal (8)

Ross

I believe the answer is:

schlepps

'tough treks' is the definition.

'school records across spain and portugal' is the wordplay.
'school' becomes 'sch'.
'records' becomes 'lps' (LP is an example).
'across' is an insertion indicator.
'spain and portugal' becomes 'ep' (I can't explain this - if you can you should give a lot more credence to this answer).
'lps' going around 'ep' is 'lepps'.
'sch'+'lepps'='SCHLEPPS'

I've seen this clue in The Independent.
