quarantine crazed runners! some set half marathon pbs at home while others log 50k doing 6000 laps around their bed
The village entrance is sealed, and people are going crazy...
In these days of not being allowed to go out, people are almost going mad from being cooped up.
Once, I firmly believed
that I could happily stay at home for at least a month.
But the reality was too naive!
So, I ended up scrolling through my phone every day,
relying on the vast number of quirky netizens for some inspiration:
Some people counted everything in their house.
Some played ping pong, ring toss, or went fishing at home.
Others pretended to go on trips at home.

Actually, these activities are nothing.
Compared to us,
the following running enthusiasts are truly going stir-crazy.
[Level 1 Running Enthusiast]
Can't go out for a run, so just run around the house.
Start with a basic 5 kilometers,running from the living room to the bedroom.
[Level 2 Running Enthusiast]
10 kilometers to feel satisfied, and also do some strength training.
[Level 3 Running Enthusiast]
The distance doesn't matter, just want to complete an online race.
[Level 4 Running Enthusiast]
Accidentally ran a half marathon at home.
Clear route, with supplies and spectators.
More importantly, accidentally set a personal best!
Achieving a personal best that many dream of, just like that.
And there are quite a few who run half marathons at home.
[Level 5 Running Enthusiast]
This is definitely a master @WestLake-Hippo, running 50 kilometers around the bed at home, nearly 5 hours of running, truly impressive~
Another netizen said: Running 10 kilometers around the living room makes you dizzy, really amazing (I calculated, this master ran about 6000 laps).
I also contacted this master, who said the 50 kilometers was a spur-of-the-moment decision. Initially planned to run a half marathon, but after 20 kilometers felt unsatisfied and decided to run a full marathon in 4 hours. Ended up running 42 kilometers in 4 hours and 1 minute, so decided to round it up to 50 kilometers...
The master also revealed that he used to run in place in the bathroom when it rained, completing several half marathons there. Why the bathroom? Because the wooden floor in the room is noisy, while the bathroom tiles are quieter. To avoid disturbing the downstairs neighbors, you can do Tai Chi, yoga, or wear cloth shoes or light shoes to minimize noise and get some exercise.

Finally, a reminder: Staying at home and reducing outings, practicing effective self-isolation, is the simplest and most effective way to prevent virus transmission. If you choose outdoor activities, try to go to less crowded places. Always wear a mask and maintain a distance of more than 2 meters from other runners.
