So if you want to run on the treadmill, be my guest. It’s not my cup of tea, but there are plenty of great runners who’ve sworn by it. My favorite example is probably Christine Clark, the treadmill-trained Alaskan who emerged from the boreal winter to win the 2000 Olympic Marathon Trials in South Carolina. If you do, don’t worry too much about whether a 7:00 treadmill mile equates to a 6:55 or a 7:05 outside. Just run, get suitably tired, and repeat. The pace, when you get back outside, will take care of itself.
In some ways, this reminds me of the debate around physical note taking versus typing on the computer.
The answer is not intuitively obvious, as there are both advantages and disadvantages to each method. Humans on average type faster than we write with a pen, which allows for the recording of more information, even verbatim transcripts. But computers are host to a number of distractions in class, including alerts, YouTube, and social media. A Word document is also a poor medium for information that goes beyond sentences, like charts and graphics. With regards to the pen, its relative slowness means the student often has to decide on the spot what’s important and what’s not, and how best to rephrase the information and organize it. This sounds like a boon for comprehension… but it requires more brain energy, which may mean important details spoken by the professor end up ignored while the brain wrestles with the information.
