Is there a rule against running with a bunch of helium balloons attached to your shoulders?
If there is, you could work on just taking a big inhalation of helium right before the start, and then holding your breath the whole race.
Ha! Holding your breath for the whole race! Not a problem, I’m sure.
I thought of that too. Then I decided that it would be too obvious. Better put them in your shorts.
What was your time after the first year that you set your goal? Perhaps you should just extend your deadline. 4:07 is something to be very proud of. Hell, I’m proud, and I don’t even know you!
Hell, you could use those long balloons used to sculpt animals, and – er – hide them.
