No.
First of all, you don't swim from Alcatraz and live. The ocean currents are so severe that they will tear your clothes right off.
So they could remain on the island for the remainder of their sentence. And if they attempted to escape, they would have to cross the sea to get to mainland; so they'd probably be dead even if they escaped Alcatraz and tried to swim away.
It can be from 1 1/4 to 1 3/4 miles, depending on the currents. Swimmers range in age from 10 to 85 minutes long.
It was considered escape proof because it was in the middle of the San Francisco bay. It was thought that if anyone did escape the prison, it would be impossible to swim all the way to the mainland. The only two prisoners to actually get off the island are claimed to have drowned.

Oban is on the Scottish mainland.
It really depends on what kind of a swimmer you are. If you can swim really well, you can probably swim really far. If you can't swim at all, you won't swim very far. I hope this answers your question.
As far as a blue whale can swim in a year
The coastline around mainland Great Britain is 11,072.76 miles. If you could literally swim right along the shoreline, that would be the distance. Because that is impossible, the answer would depend upon how far off-shore you swim.
