I have a treadmill, and my normal routine is to use it for 20 minutes, on a programme that gives me...
- 1 min at 2kph
- 18 mins alternating between 6kph and 9kph (one minute each)
- 1 min at 3kph
Now the winter is receding, I'd like to swap in some walking outside instead, but am wondering how long I would need to walk to burn up the same number of calories. To clarify, I'm trying to compare my running on the treadmill with walking at a normal walking pace.
I realise that there are too many unknowns to give an accurate answer, but was hoping someone would be able to give me a rough guide.
