1. Wind direction.
Take wind direction of monsoon into consideration. You need more energy and will feel more laborious to cycle against the wind direction.
Generally, the shortest route to destination is the best. But this idea isn’t always right. A straighter route or flatter route is often the better route.
You don’t enjoy cycling when it rains cats and dogs, yes? And do not forget to protect yourself from the sunburn.
4. Your waist.
You’d better bend your waist while cycling. This posture will give you less wind drag.
5. Wear your helmet and gloves.
6. Bring your raincoat.
