Obviously you'll need all the stuff you are planning to take on the race. We will pick up one hand-sized piece of luggage from the start camp and deliver it to the finish camp at the race's conclusion. You need to label that luggage. You can bring a change of clothes and your favourite scented candle, or whatever else you fancy.
There will be no power at the start camp, and very limited power at the finish camp. The crew's satellite phones and laptops will take priority over any riders' gadgets. You may well be desperate to communicate your survival to the world but you will most likely have to wait until we return to UB.
