A mixture of flat roads and gentle hills.
What are the roads like?
The roads are largely of a decent quality however there are places where they fall into disrepair. Notably, the road surface quality on day 3 is pretty awful but the scenery is stunning. This is all part of the challenge. Around the cities there can be heavier traffic but in the countryside traffic is thin. The roads mostly have distance markers every kilometre which is handy for ensuring that you are on the right road.
What type of bike should I bring?
A stronger bike like a light tourer or hybrid or even a mountain bike (provided it's geared to allow you to go fast) would be a better idea - if you use a road bike you would need to be very careful of rough patches (it's not really recommended, especially given the poor surface quality on day 3...however it has been done. You have been warned...)
Where does the Challenge start?
Close to the Gongbei Port border with Macau (note, the border is known as the Portas do Cerco in Macau).
Which flights should I book to get back to HK?
Dragonair and Hong Kong Airlines operate direct from Guilin to Hong Kong. China Southern and Hainan Airlines operate direct to Shenzhen. Check with ctrip.com. Those wanting to save their pennies may consider taking a bus or a train back.
Do I need a Visa for China?
Yes, the Chinese consulate is located in Wanchai and obtaining a visa is very straighgorward. Processing can take five working days - do not leave this to the last minute. Chinese Consulate: 7/F, Lower Block, China Resources Building, No 26 Harbour Road, Wan Chai. Tel: 852 34123 2424.
How do I get to the start?
The easiest way, if you are travelling with a rucksack that does not weigh much, is to take the ferry from Hong Kong to Macau, then ride carefully the 3 kilometres to the border which you must cross on foot. Alternatively, you can make use of a taxi. The ferry service from Sheung Wan direct to Zhuhai have told us that they will require you to pack your bike in a box however Turbojet to Macau do not require this which could be more convenient. It is possible to take a ferry direct from Hong Kong International Airport to Macau and Zhuhai.
