1.Tips for Cycle Trips
Cycling has many advantages as a form of travel,as it is the fastest way to travel by human power,and slow enough to allow the type of local involvement that is impossible with powered travel.Cycle travel is a cheap form of transportation.
Distance
On level terrain(地形),without a headwind,a cyclist of average fitness on a touring bike can comfortably cover 60-120km a day.Distances of up to 250km a day are possible,but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit.For many80-100km a day will be the most suitable distance to aim for,as it will give a sense of achievement and also lea ve plenty of time for meals and activities.
Geography
The gradient(坡度)of the trip will reduce your range.A basic rule is that for every 100metres of altitude you climb,you should add an extra 15 minutes to your journey time.In hilly or mountainous areas,the easiest routes for cycling are downstream along major rivers,as they will be downhill overall.However,it is worth bearing in mind that the most scenic routes often come from hilly terrain(地形).
Eat
Food choice depends largely on where you are,so see the respective(各自的) sections for more information about foods.On long trips away from major towns,there may be little quality food available,so be prepared to live on candy bars,prepared meat products and the like (and so on) if the need arises.
Sleep
While you can take a tent with you,many hotels and especially campsites can accommodate (provide …a place to stay)cyclists.However,there are also some hotels that may be less used to accommodating cyclists.
