I have a question concerning treadmills. I joined a gym 3 weeks ago and did 3 runs on the treadmill until now (the rest has always been outside in the park). The first run was ok, a bit slow (5k in 35 min something) but I had to figure out how this thing works (and I have seen enough funny videos of people falling of their treadmills to be careful). The second one was pretty good (5k in 32:53min) and I ran about half of the time at 9.3-9.5 (I guess it's km/h... not written anywhere). The last run was horrible (had to stop after 30 minutes (4k) as I suffered from house dust mite allergy for two days combined with a nice beginning cold on the day of my run.
Nevertheless, I have the feeling that a run on a treadmill is like cheating... it does a lot of the work, doesn't it? I put the incline on 1.5-2.0 to try to imitate the conditions outside. I'll also try to run not slower than 8.3 (in the first five to ten minutes of the run) and then faster than 9.0. I'm also sweating a lot during the run and feel that it's hard work but I still feel it's so much harder to run outside.
Does anyone have the same feeling? Is it just the overly self-critical sloth in me telling me that it's cheating to run on a treadmill?
