This reminds me of the time my pops told me "soccer was a soft sport and anyone could do it."
So I took his ass out to my 30+ group I play with and told him "gimmie 15 minutes or complete two forward passes...which ever comes first."
Old ass was holding his sides after the first two attacks.
Look at this, people try to attempt to keep up with Eliud Kipchoge jogging pace for his long distance world record. Some people are literally sprinting.
These atheletes doing feats that are nearly superhuman. Imagine keeping that pace for 20+ miles.
