Running has become a fashion, rather than passion.
Being a runner for more than 15 years, I learn to respect individuals for sharing the same route as me, just because...anything can happen on the race day. You can't expect first class treatment just because you have paid for the race. In fact, there are many things you can do as a runner.
1.
Proper hydration- If you drink properly, you never need to use the washroom aka portable loo. I ran many races but it was only during my first full marathon I stopped at KM32 for the loo. Still I believe that I could have planned my hydration strategy better that I didn't need to stop even for full marathon. In the end, I don't have to worry about long queue to use the washroom.
The trick is, know your body well, drink adequately to replace lost fluid, don't over hydrate.
2.
Proper start- Know your running speed. If you are relatively fast, start ahead; otherwise, start at the middle or back of the pack. Starting at the wrong point can be dangerous, stampede is the last thing you want.
3.
Behave yourself- I hate couples who hold hands and walk during a race. I also saw people who stop suddenly during a run...just to take a selfie. These are the reasons why I seldom join runs below 20km unless it's really cheap and I am in good form to outrun the general crowd.
4.
Give signals- Just like driving, you keep to the left of the road to give way to the faster runners unless it very crowded. If you want to stop to tie your shoe lace, please signal before you move to the left of the road and signal to stop. This is very important when the runners around you are running at similar pace.
5.
Drink station- Normally the first table will be cramped with thirsty runners, I would suggest to stop at the further tables, quickly choose a cup, move away and drink.
In a nutshell, Malaysians have improved (according to my observation). Good job and happy running.
