Marathon

In 490BC, The Greek city states were hard at war with the almighty Persian Empire. One well-known battle (out of many) is the Battle of Marathon, fought between about 10,000 Athenian soldiers (with some Plataean reinforcements) versus 26,000 Persian soldiers. Despite the Persians having superior numbers and cavalry, the battle concluded with a decisive victory to Athens thanks to a well-implemented flanking strategy and the temporary absence of the Persian cavalry at the base camp. The battle was a turning point in the First Greco-Persian War and the crushing defeat drove the Persian invasion force off Greek lands for ten years.

The popular story goes that a runner named Pheidippides was sent from Marathon to Athens after the battle to bring the good news, as the people of Athens were still gripped in fear that the Persians would directly strike the city soon. It is said that Pheidippides ran a distance of about 40 kilometres back to Athens and on arrival cried out “We have won!”, then collapsed and died from exhaustion.
When the modern Olympics was being designed at the late 19th century, the organisers decided to use this story to inspire what we now call the marathon – a 42.195km endurance run. The story was to recall the glory of ancient Greece and the heroic act of Pheidippides (also referred as Philippides in some texts).

Unfortunately, the story is a romantic amalgamation of two separate stories. But then again, the actual story is just as incredible.
Despite the decisive Athenian victory at the Battle of Marathon, the war still raged on and the Persians changed directions and headed for Athens instead. The Athenian army marched swiftly back home to pre-empt the Persian landing force. They marched 40km within a day – an amazing feat considering the fact that they just fought a massive battle and were armoured from head to toe.
The runner, Pheidippides, actually ran a distance of 225 kilometres from Athens to Sparta seeking reinforcements before the Persian army landed in Marathon (i.e. before the Battle of Marathon). He then ran back to Athens, meaning he ran roughly 450~500km within a few days. There is not much historical evidence of whether he actually ran this far in such short time but there are some anecdotal recordings.

The world record for the fastest marathon is 2 hours 3 minutes 23 seconds (as of 2014) by Wilson Kipsang of Kenya. The world record for the longest marathon ever run is set by Shiso Kanakuri, who started the marathon on July 14, 1912, during which collapsed from heat exhaustion around the 27km mark. He had to withdraw from the race, but could not bear with his “failure” all throughout his life. In 1967, he challenged himself again at the age of 75 to finish the remaining 15km, eventually setting the record time for the longest marathon ever run – 54 years, 8 months, 6 days, 5 hours, 32 minutes and 20.3 seconds.

Rain

Let’s imagine that you are walking outside, when rain clouds catch you by surprise and suddenly pour down on you. Assuming that you have no umbrella or anything to cover yourself with, is it best to run back home or walk back? Or to elaborate, should you walk and spend more time in the rain, or should you run, which means you will run into rain sideways?

There are two ways you can get wet in the rain: it will either fall on top of your head, or you will run into it from the side. The amount of rain that falls on your head is constant whether you are walking or raining, as the entire field you are travelling through is full of raindrops. Therefore, one would naturally think that running would not add much benefit as you run into more rain by moving faster, as you essentially hit a wall of raindrops.

But this is not true. No matter how fast you travel, the amount of rain you hit sideways is constant. The only variable that affects the amount of rain you hit sideways is the distance you travel. This is because the amount of raindrops in the space between you and your destination is constant.

Summarising this, the wetness from rain you receive is:

(wetness falling on your head per second x time spent in rain) + (wetness you run into per meter x distance travelled).

Since you cannot really change how far you are from your destination, the best way to minimise getting wet is to run as fast as you can to minimise the time you spend in the rain.

Then again, this is only the most practical option to keep you dry. If you are feeling particularly romantic or blue, then feel free to stroll through the rain, savouring the cold drops on your face (or wallow in the sadness that is your life).

For Them

Eat, for those who are starving.
Run, for those who cannot walk.
Breathe, for those who are suffocating.
Dream, for those who have lost hope.

See, for those who are blind.
Listen, for those who are deaf.
Feel, for those who are numb.
Speak, for those who are voiceless.

Laugh, for those who are crying.
Love, for those who are heartbroken.
Live, for those who are dying.
Be happy, for those who are miserable.

There is no excuse for not doing what you can. 
There is no excuse for trapping yourself in a box.
If it does not harm you or others, then do whatever the hell makes you happy.
