4.5mph is a mental pace so I'd assume the distance is less.
If I stomp solidly for 90 minutes I'll cover five and a quarter miles, that's 3.5 miles an hour which is a pretty good average pace on grass. Keeping 4mph up on tarmac is tough for longer periods.

I can do a sustained 4mph
but I've got longer legs than rswipe, so it's easier for me.

On tarmac 4mph is easily doable for a couple of hours
out in the country you'd be doing well to keep up 3.5mph on undulating ground.

oh no don't depress me!!!
I thought it was 7 miles because that is what car says when i drive it, maybe that was rounded up or i take a shortcut on foot... I do walk quickly but it's not exactly powerwalking.

Dooooooom. Not even your second lovely parcel is going to cheer me up now (but THANK YOU anyway).

So nearly just walked into a tree typing this, a whole number 9 bus is laughing at me.
