Biden and Trump are both "running" for POTUS. Who would win, if they had to physically "run?"?

It’s NFL Combine time.
For those unfamiliar, it’s when all of this year’s draft prospects go through a long series of tests.
Mainly things like 40 yard dash times, broad jump, bench press, cone drills etc.

This time of year, many of my friends will be betting cash, on who can beat who in a foot race.

Many average citizens will attempt some of the drills, to see where they stack up.

They are obviously, mature in age. So let’s keep it simple.

A 40 yard race.
A 100 yard race. (Yards are practically meters.)

Which senior candidate, is REALLY best fit?
