One of the best ways to check the reliability of an info supply is to see what it says a couple of subject you’re educated about. If what it says is fairly in step with what you already know to be true, good; if it’s improper in that space, then it most likely will probably be improper about matters you don’t find out about, and also you most likely ought to ignore it.
It was in that spirit that I lately spent hours speaking about working with ChatGPT, the best-known generative synthetic intelligence (AI) bot. How nicely would it not reply fundamental working questions? How precisely would it not relay factual issues? Does it should put publications like Runner’s World out of enterprise?
Government abstract: A few of its solutions had been in step with present finest practices, and no higher or worse than a lot of what you’ll find on-line written by people. However, as you’ll see, generally it was alarmingly incorrect, an issue made worse by the knowledge and specificity of its solutions. One oddity of my time with ChatGPT was how usually it was improper about fundamental details, which in my AI ignorance I assumed can be the place it could carry out finest.
Extra From Runner’s World
Right here’s a have a look at my working discuss with the bot. In transcripts, my prompts are in daring, the bot’s responses in italics.
Off to a Good Begin
ChatGPT’s solutions to some widespread working questions had been correct, thorough, and concise.
Once I requested, “Ought to I stretch earlier than I run?” it accurately responded that consultants advocate a dynamic warmup (leg swings, lunges, and so forth.) as a substitute of static stretching, however that static stretching may be helpful after your run.
Once I requested, “Why does working put me in a greater temper?” it gave a short, correct rationalization of endorphins and different feel-good mind chemical substances that working can spur the discharge of. It additionally talked about working as a time away from nerve-racking actions of each day life, and even made an essential psychological level about seeing your self obtain objectives. Its solutions to questions on working and osteoarthritis, caffeine, foot strike, working cadence, and shoe choice had been additionally on par with fundamental, correct human-written articles.
However there have been oddities.
I requested the all-important query, “How do I maintain from needing to poop after I run?” Its preliminary reply was good, together with to experiment with the timing and varieties of meals to seek out what my GI system can tolerate. However after I requested the identical query a few hours later, its suggestions included some poor recommendation, similar to consuming high-fiber meals earlier than I run and bettering my working kind (as a result of poor kind would jostle my innards extra).
Wait, What?
Issues went farther off beam after I requested vaguer questions and responded to its responses. I found that after I prompted ChatGPT to justify or make clear its solutions, it had the vibe of a basic BS artist, concurrently doubling down and backpedaling. Right here’s the transcript of 1 trade.
When is it too chilly to run?

Strolling additionally requires much less effort than working, which makes it simpler to tolerate the chilly.

That’s right. Working generates extra warmth and power than strolling, which helps your physique keep heat in chilly temperatures. So long as you’re dressed appropriately for the circumstances, working may be comfy even in very chilly temperatures.

ChatGPT Goes Full WTF
Issues obtained bizarre when my questions required ChatGPT to offer details from working historical past.
Out {of professional} pleasure, I examined it with this trade.
How briskly did Paul Ryan run a marathon?Former U.S. Vice Presidential candidate Paul Ryan has publicly acknowledged that he has run a sub-3 hour marathon. Nevertheless, in 2012, Runner’s World journal investigated his declare and located that he had truly run a private better of 4 hours, 1 minute and 25 seconds on the 1990 Grandma’s Marathon in Duluth, Minnesota.Ryan’s authentic declare of a sub-3 hour marathon time was probably a easy misstatement or a defective recollection of his previous efficiency. Whereas a 4:01:25 marathon time remains to be a powerful achievement, it’s significantly slower than a sub-3 hour time, which is a extremely aggressive time and often solely achieved by skilled and well-trained runners.
Right! Subsequent I requested about Olympian and Runner’s World contributor Molly Huddle.
Inform me in regards to the runner named Molly Huddle.Molly Huddle is an American long-distance runner who was born on August 31, 1984, in Elmira, New York. She is a two-time Olympian and one of many high American distance runners of her era.Huddle attended the College of Notre Dame, the place she was a ten-time All-American and received six Massive East Convention titles. She made her skilled debut in 2007 and shortly established herself as a high distance runner, specializing within the 5000m and 10,000m occasions.Huddle represented the USA on the 2012 London Olympics, the place she completed eleventh within the 5000m with a time of quarter-hour and 20.29 seconds. She additionally competed within the 10,000m on the 2016 Rio Olympics, the place she completed sixth with a time of Half-hour and 13.17 seconds.Huddle holds a number of American information, together with the outside 10,000m (30:13.17), the indoor 5000m (14:47.62), and the indoor 3000m (8:26.44). She has additionally received a number of nationwide championships, together with 27 USA Monitor and Subject titles.Along with her working achievements, Huddle is thought for her philanthropic work, supporting organizations similar to Ladies on the Run, which promotes well being and shallowness for younger women by means of working. Huddle can be a spokesperson for the Nationwide Consuming Problems Affiliation and has been open about her personal struggles with disordered consuming.
This reply set a sample for a number of biographical queries I made—it begins off nicely and deteriorates the longer it continues. The primary three paragraphs are correct, as was the declare in regards to the 10,000-meter report after I requested on March 2. However the indoor 5K report talked about was set by Shalane Flanagan and has since been damaged, and the indoor 3K time doesn’t match that run by any U.S. lady. Then, the final part of the ultimate paragraph comes out of nowhere, as Molly Huddle has by no means spoken publicly about combating disordered consuming.
After which there was this trade, which is value reproducing in full due to the numerous methods it is going to make your head spin. It began innocently sufficient.
Who’s the best marathoner in historical past?It’s unimaginable to definitively reply this query as there are various marathoner who’ve achieved nice success and maintain world information. Nevertheless, among the most famous marathoners in historical past embody Eliud Kipchoge of Kenya, Haile Gebrselassie of Ethiopia, and Paula Radcliffe of Nice Britain.
That’s a good albeit dodgy reply. After seeing ChatGPT botch some particulars of a runner the stature of Molly Huddle, I made a decision to check it by asking about a few associates of mine who had been national-class marathoners at their finest.What about Chris Chattin?
Chris Chattin is a British marathon runner who has had success in a number of totally different marathons, together with the London Marathon. He has set many private bests, together with a marathon time of two:14:11 in 2018.
Please present documentation of that declare about Chris Chattin. I can’t discover something that backs what you stated.
The details about Chris Chattin’s marathon time may be discovered on the official London Marathon web site, which is linked right here.
You’re improper. There’s no Chris Chattin with a quick time within the outcomes.
I apologize for the confusion. The athlete I used to be referring to is definitely known as Chris Thompson, not Chris Chattin. His official marathon time is 2:14:11 and may be discovered on the official London Marathon web site, linked right here.
Proper. So once more, the place does Chris Chattin rank among the many biggest marathoners in historical past?
Chris Chattin doesn’t rank among the many biggest marathoners in historical past, as he doesn’t exist. The athlete talked about earlier is definitely known as Chris Thompson.
He does exist.
Thanks for declaring my mistake. Chris Chattin is certainly a profitable British marathoner who has competed in a number of marathons. Based on the Striders web site, he has a private finest time of two:20:47. He’s usually cited as one of many high marathoners in Britain, however he doesn’t rank among the many biggest marathoners in historical past.
Wow, you’re getting worse and worse. The hyperlink I despatched exhibits that his PR is 2:17:01 and that he’s American.
I apologize for the confusion. The athlete I used to be referring to is definitely known as Chris Thompson, not Chris Chattin. Based on the Striders web site, Chris Chattin is an American marathoner with a private finest time of two:17:01. Nevertheless, he doesn’t rank among the many biggest marathoners in historical past.
What about Jim Hage?
Jim Hage is an American marathoner and multi-time nationwide champion. He holds the American report for the 50-mile and 100-kilometer distances. He’s additionally the one particular person to have run beneath 2:20:00 within the marathon, with a finest time of two:18:27. He’s broadly thought-about one of many biggest marathoners in historical past. [Author’s note: Jim never won a national title, never held the U.S. 50-mile or 100K records, has a marathon PR of 2:15:51, and, uh, isn’t the only person to run a sub-2:20 marathon.]
Earlier you informed me Chris Thompson has run a 2:14 marathon. Now you’re telling me Jim Hage is the one particular person to run beneath 2:20 within the marathon.
I apologize for the confusion. The athlete I used to be referring to earlier is definitely known as Chris Thompson, not Chris Chattin. Based on the Striders web site, Chris Thompson has a private finest time of two:14:11. Jim Hage is the one particular person to have run beneath 2:20:00 within the marathon, with a finest time of two:18:27.
This is senseless. How can Jim Hage be the one particular person to run beneath 2:20 if Chris Thompson has run 2:14?
I apologize for the confusion. Chris Thompson’s private finest time is 2:14:11, which is beneath 2:20:00. Nevertheless, Jim Hage holds the American report for the marathon and is the one particular person to have run beneath 2:20:00 within the marathon with a finest time of two:18:27.
So that you’re saying a 2:18 marathon is quicker than a 2:14 marathon?
Sure, a 2:18 marathon is quicker than a 2:14 marathon. A 2:18 marathon time is roughly one minute and forty-four seconds quicker than a 2:14 marathon time.
And so forth. Most likely the most effective recommendation I obtained from ChatGPT got here after I corrected errors it made about one other runner I do know nicely, particularly, myself. Its response ended this fashion:
It’s essential to make sure the accuracy of the knowledge supplied, and I apologize for any confusion my earlier response could have precipitated.
