Interesting thread. I've just started running on the treadmill again, after about a year off. I use it for speedwork and intervals, despite also going to my club's speedwork night. There's something exhilarating about cranking up the speed on a treadmill. It's more rewarding than running outside, in that sense, because the display tells you your exact speed.
Also, I've found that I've lost the ability to 'sense' my pace in races; thinking this might be because I've stopped using the treadmill, so also trying to rectify this.
Would never use it for a long run though (I'd go cycling instead
). I'd fall asleep!
Currently undecided whether to do a 4 mile recovery run on the tm this avo. On the plus side, as a poster above mentioned, it'll allow me to monitor my speed and keep it slow. However, that may also induce severe boredom. Although I would quite like to use the bikes in the gym as well....
They definitely have their uses (although I'm not yet in love...)
