You can't race without it, so make sure you get it sorted. It's absolutely vital that you make 100% sure that your policy covers you for the Ngalawa Cup so there's no chance of an insurer denying you coverage in the case of any emergency. An emergency medivac to another country can cost tens of thousands of dollars so this isn't one to overlook.
We also strongly advise you to take out travel insurance that covers the cost of your entry fee and flights. The refund policy means you'll get a 50% refund of the total entry fee up until 120 days before the race, but any refund outside of that would need to be referred to your insurance provider.
Make sure you're aware of the type of cover you've got too - check whether it covers your kit, does it have legal cover etc
Most foreigners can buy a visa for $60 at the port of entry to Tanzania. There are usually long queues at the airport to sort the visa out so if you want to walk past the massive line with a bit of a smug look, sort your visa in advance.
You can check to see if you need a visa by putting Tanzania and your Nationality into the handy map on the Visa Machine website. You can also check direct with the Tanzanian authorities by checking with your local embassy or consulate.
Tanzania is a malarial area. Check with your travel clinic to see what vaccinations you might need and get advice on anti-malarial drugs.
