Final Triathlon not showing up?

I known it says that the final triathlon is unavailable for Mike and T while they're exiled from the city, but does it not show up at all until they're allowed back in?  I've completed the first two, but the third one isn't currently showing up for Franklin on the map either.  I've completed the second one with Frank twice now hoping the third would pop up, but no such luck.  I had an issue with the final street race not showing up for Frank on a previous play through, but finishing the second to last street race a second time remedied that.
