Map, tent, water, food: check. All needed to scale the snow-capped peak of Africa's highest mountain Kilimanjaro.
Bat, ball, stumps, pads: check. Also needed when you're hoping to break the world record for the highest game of cricket ever played.
Two teams are taking part in a gruelling eight-day trek up the vast extinct volcano, to play a full Twenty20 game in the ice-covered crater just below its rugged peak, at 5,785 metres (19,000 feet).
"Kilimanjaro is definitely not somewhere I thought I'd bowl a few overs, but the challenge thanks to the altitude is huge... bring it on!" English bowling legend Ashley Giles, one of the captains of the mixed professional and amateur teams, told AFP.
The eccentric dream, to hear the thwack of willow on leather over three miles (five kilometres) high, was thought up by expedition leader David Harper, a British hotel real estate consultant.
Harper said he planned the match in a bar after his wife told him the "only way he was ever likely to play cricket at the highest level would be if he played on the top of a mountain".
After a week of climbing that began Saturday, teams plan to reach the peak at dawn on Friday.
But they then must play a full game in the crater of the dormant volcano, laying down a plastic track for the wicket over the ash before playing in the thin, freezing air surrounded by vast blocks of ice.Rain won't stop play
South African icon Makhaya Ntini, the country's first black Test player, is also taking part in what he called a "massive, exciting challenge".
There will be half the level of oxygen than at sea level for the game, doubling energy needed for the match.
The teams are taking oxygen tanks for medical emergencies.
But while flurries of snow may be possible in the bitter cold, organiser Harper promises that at least "rain is unlikely to stop play".
Qualified umpires will ensure the charity game is played properly -- and is eligible to break the record.
The mainly English team also includes players from Australia, Canada, Kenya and South Africa.
"It is a incredible challenge," said Heather Knight, the other team captain, who back home is vice-captain of the English women's team.
The expedition of over 30 players and umpires -- and an AFP journalist -- are making the trek to the top, along with a Tanzanian support team of over a hundred, helping to carry the kit and food up to the top.
The current record for the world's highest game is 5,165 metres (16,945 feet), played in the Himalayas at Everest base camp in Nepal in 2009.
If successful, the game on Kilimanjaro will be over 600 metres higher.
