Can anyone help with the parsing of these clues:
12a You'll get to end of race, breaking what's seen as old record (7-5) = SEVENTY-EIGHT
3d Swimming metres in old harbour potentially dangerous activity (7,5)
Thanks jazzgirl and chrisg. Would never have got 12d.
Sorry, meant to add that I also had the answer EXTREME SPORT but couldn't parse that one either. Any thoughts?
