Arrive in Nouakchott anytime.
Our event is officially recognised by the Mauritanian Government. The visa is on available online for everyone competing in the event. After that, just get yourself to Mauritania's capital, Nouakchott.
My team will meet you at the airport, and drive you to our starting hotel. We have a briefing at 6pm today, and then a group dinner with all the other maniacs taking part.
NOTE:
You can fly here via Paris (Air France), Casablanca (Royal Air Maroc), Istanbul (Turkish Air), plus a lot of others. I normally fly on Turkish Airlines because it's a direct flight from Istanbul. For Europeans, it may be easier via Casablanca, Morocco.
