Treadmill recommendations?

When I looked into it I found that decent quality treadmills are very expensive. My wife has one but I can't use it as the track keeps slipping when I run on it (and the max speed is not as high as I would like).

I run outdoors on unlit lanes using a headtorch (and reflective top/visibility lights) and that works well for me. Might it be an option for you?

i use mine 3-4 times per week in winter for marathon training as i live in a rural area with no street lights and prefer not to run on the dark roads (nor drive to somewhere with street lights), i just do one run at the weekend outdoors to remember what non-treadmill running is like

main consideration is probably the size of the actual running deck (length+width) go as big as you can and also the motor again bigger the better

i bought a nordic track (other brands available) four years ago for about £700 new and it's never given me any trouble, only maintenance is a monthly squirt of lube

i figured even if it only lasted a couple of years it was no more expensive than joining a gym just to use a treadmill and there's the benefit vs. a gym you don't have to travel outside your house to use it + you can do what you want so running half naked with tunes blaring etc. if that's your thing

in my case potentially crap winter weather (ice for example) and also rural roads with no streetlights where people have a habit of driving at 70 mph were both reasons to plump for the comfort/convenience of a treadmill for winter training purposes
