In Reply to: Lap swimming in Ubud posted by Francesca on Tuesday, 19. April 2011 at 16:38 Bali Time:
If you do a google search - lap pool Ubud, quite a few hotels come up with having one (though some less than 25m)
Perhaps email them to enquire & also to see which is closest to you
eg
d'Omah - 45m lap pool
