Fart & Furious: flatulence as acceleration booster possible?

It's the Olympics, and it'll be one the world won't soon forget. The sprinters are in position on the starting blocks, the signal is given and the runners are off! However, one man gives off a fart so huge that it significantly boosts his acceleration. This mother of all farts propels him all the way to a first place finish and a trophy on a pedestal. Cue a training montage flashback where our protagonist learns the art of fine muscular control in a remote mountaintop monastery.
My question is this: is it mechanically viable for a male athlete weighing approximately 80kg to use rapid anal gas expulsion(AKA flatulence) as a form of nitro boost?
Pain points I've identified:
Fart propulsion might have too low a thrust-to-weight ratio for this purpose
The human body might not be able to store enough gas for this purpose

More useful for a swimmer I would think if it's a white male athlete.... purple female would be a different story

Unless he had a hole in his pants for the gas to escape from, most of the speed of the gas would be lost since it needs to be pushed through the fabric.

I don't think it is viable.
If you want to propel the athlete of mass m to certain velocity v starting from rest, you need to provide a momentum $P = m_a cdot delta v_a$.
The same momentum has to be given to the expelled gases. The average bowels should be around 10 meters long, and let's assume they have an homogeneous radius of 1 cm, it means the available volume of gas is about 10 liters, accounting for a mass of about 6 grams, if we assume it is fully made of methane.
It follows that, to speed jump the athlete at 10 m/s that gas would need to be expelled at $delta v_g = m_a cdot delta v_a /m_g = 80 cdot 10 /6 cdot 10^-3= 130 km/s$.
Though I am not aware of any scientific study on the topic (if it exists, please submit it to IgNobel award committee), I am fairly confident that would be sufficient to blast away the athlete's lower body.

mistupid.com/facts/page070.htm "Farts have been clocked at a speed of 10 feet per second." - that's around 11 km/h or 0.003 km/s. Just for the sake of completeness.
