Last week we ony ran 10km -recovering from running the marathon in Dubai - will run further this weekend, though if you want to stop at 10km as some do that is not a problem.

As for the race - I am thinking November this year because unless someone has organized such an event in Qatar before I think that there will many barriers to anything organized. I certainly won't be able to do it by myself

Might even consider 10 miles or 16.6km instead.
