Running on a NordicTrack T20.5 treadmill
I joined a local gym in mid-June for 3 months in order to try treadmill running and see if I liked it. The gym has other equipment I use like the Concept2 rowing erg, elliptical machines and stationary bicycles. I enjoyed the warmth of the gym so decided to buy a home treadmill. After a little internet research I chose the NordicTrack T20.5 ($1999 delivered including the iFit module and 12 months' membership of iFit). The treadmill has a 3.5 continuous horsepower motor 0 to 15% incline (8% is bloody hard!) and 0 to 3% decline. The decline feature is great for downhill training (working the quads) and for simulating rolling hills. There's a Youtube video showing the T14.2 model being run on at the top speed of 22 kph. Scary!
So how am I liking it? It's great! Perfect for the distances I want to run — usually 5k (although I completed the 'Isle of Arran' iFit course the other day, which was 8.09k). The iFit module links the treadmill to your laptop or tablet computer. As you run a course (there are many different ones available — or you can design your own), images from Google Earth street view and matched to the treadmill's speed. The images are downloaded instantly every few seconds so not video-like but good enough for the bush. The viewpoint is quite high too, perhaps the height of a bus, so you get a tall view of the scenery you're running through. The treadmill's incline is automatically adjusted, which I've found is sometimes exaggerated from real world courses. Because of this I've been preferring flat courses.
I've been finding treadmill running a little harder than running outside. Heart-beats per kilometre seem to be a little higher on the treadmill — perhaps because the temperature is so warm! I noticed when I turned on the built-in fan to high speed half way through a steady-paced run that my heart-rate declined! The treadmill also demands quite a bit of concentration to stay in the same position relative to the console. Drifting back could be very dangerous! For this reason I've been conservative when choosing speeds for steady runs and interval sessions. As well as the iFit and in-build programmes there are some good treadmill workout ideas on the web — for example, ones such as this on Carrie Tollefson's Youtube channel.
