In a way it would make more sense to run in shoes that make you slower for the same effort or make you expend more effort. Ideally, you could just run around the block and it would be as much effort as 10km. Without the risk of something going wrong mid route leading to being stranded/soaked/injured 5km from home. Same with cycling.

Probably not for running because it would affect how you run in a way that wouldn’t give you the benefits you’d want above just running the full distance. Probably the only thing I’d recommend for “running slow but getting good benefits” would be off-road running. The softer impact and uneven ground reduce stress while giving you a joint workout that supports road running, in my opinion.

For cycling, just ride up a hill if you’re that desperate for punishment :p

Firstly, consider why so many people like running outdoors when they could just run on a treadmill and watch tv indoors? Secondly, note that running injuries don’t tend to suddenly appear and cripple people half-way through a run. They are more likely to appear at the start, sometime afterwards, or to gradually progress in a way that might lead one to reducing volume or resting.

Some runners train with parachutes, sleds, weight vests, or rucksacks which all make even short runs feel much harder. Ultimately it depends on your goals. Is it cardiovascular fitness? Build muscle? Live longer? Feel better? See a lower number in a chart?
