On June 14, an ambitious crew of four locals will climb into their SUVs, bid farewell to loved ones, and head towards the Shenzhen border.
If all goes according to plan, they will step out on to the streets of London one month later after driving 25,000km through some of the most remote parts of Asia - all in the name of fun and charity.
And, for those without summer vacation plans, a few seats are still available.
Bobby Man Wai-hung is co-ordinating the 'Drive for Hope' project, which will take his team across the mainland to Kazakhstan, to Russia, through Europe to France and finally to Britain. He has driven to Tibet a few times before, but this is his most ambitious trip.
The team members are packing a supply of food and water but won't be roughing it completely - they plan to stay in motels or hotels every night for safety. Mr Man described their trip as 'backpacking on the road'.
'We'll have tour guides escort us to the border when we get to Kazakhstan and Russia, but these two places are the only worries we have on our safety,' he said.
