“How far and how fast would I have to walk, cycle or swim for it to be the equivalent of running a marathon?

Answer 1

It's 26 miles roughly, but I think strictly speaking it's like 26.2 or something

Answer 2

a marathon is 26 miles and 385 yards. isnt what your asking essentially the same as which is heavier a ton of feathers or a ton of bricks?? 26 miles is 26 miles whether u swim, walk or run it

Answer 3

It depends on your weight, but if your about 12.5 stone, and you base it on calories used, and you jog the marathon and it takes about 6 hours. You'll have to:

Swim about 12.5% longer
Walk briskly about 70% longer
Cycle on the flat about 53% longer

To use the same calories.
