Hang on to your bladder.  Before we talk more about peeing like a racehorse, we need to understand a bit about racehorses in general. 

Due to cheating in the horse race industry, racehorses are tested for drugs. The horse is led into a special stall and under the watchful eyes of a steward, has its urine collected. Nobody wants to be standing around for hours waiting for a horse to pee. To stimulate the racehorse to urinate usually all one has to do is to is rustle some straw beneath the horse and it will stretch out and pee. This method is used anytime a urine sample is required from a racehorse, or to have it pee at a convenient time.

Now.. you can combine this with the fact that racehorses have to drink a lot of water to keep their body in peak physical form and you see why it might just urinate with some force, and volume. A racehorse would typically urinate every 4 hours, producing up to 2 gallons of urine a day.  No matter what, you will never piss like a racehorse, humans only urinate a quart or two per day.

 

Some drugs are legal to use on racehorses, but one drug, Lasix (although legal in certain amounts) was once used to get horses to urinate more than they should before a race. The theory behind the use was that if the horse peed enough it would be lighter, and therefore, faster in the race. Indeed, Lasix is a diuretic. Today it is controlled and used to stop horses from bleeding from their nose during a race.

The saying “Whiz like a racehorse” undoubtedly came forth from the time when Lasix was used as a diuretic to make racehorses pee more than usual.

Worth noting is that horses who race on Lasix have it noted on the racing form.  First time Lasix users usually are noted with a 1L, and after that just an L, typically once a horse is given Lasix for a race, they are always given Lasix for future races.

    Doesn’t seem like less urine would make a horse faster. What it a myth maybe. And to drug them for it? Poor horses and too many drugs. At least they don’t do it anymore. Interesting post and pic.

    I take Lasix does that mean I really do pee like a race horse?

    Fascinating, I am not knowledgeable about race horses, so it isn’t surprising that I hadn’t heard this before. I learned something new, which is always good.
