I'm not sure if any of that is true, I just found it interesting. In my experience, with my treadmill, I feel like I'm putting in a lot more effort to run at the same pace I would outdoors. Looking at my streak stats it wouldn't seem like that'd be so, as my two outdoor runs are significantly slower than my treadmill runs. I attribute that to being the first runs after a 2 month hiatus... And not bein used to running in 10 degree weather, on a snowy/icy surface, and wearing 50 pounds of clothing. It's supposed to be warmer on Monday so I'm hoping to get in another outdoor run.
Back to the experiment... I wanted to see how different the treadmill and Nike+ app would be, if at all. I ran for 4 miles (according to the treadmill) between 5.6 and 6.0 mph. I finished in 41:36.
The Nike+ app, however, said I ran 4.5 miles in 41:13 (I didn't start the app until the treadmill was up to speed. I also stopped the run at 1 mile to use the ladies room so that's why there's a time discrepancy).
I really think the truth lies somewhere in between those two. Prior to my stress fracture, I was frequently doing my shorter runs at about a 9:00 average pace, so I know that the 9:09 pace is possible... I just have a hard time believing that I could achieve those times again with only 2.5 weeks of training after essentially 3 months off.
That outdoor run I'm planning on Monday? I'm going to test the Nike+ app (using the indoor function) against the Garmin. Can't wait! I love stats and numbers.
My hip was really bugging me after the run (again) so I spent some time on the foam roller. I think I've finally isolated the trouble spot.
Apparently Mercedes has some trouble spots too:
It's a little hard to see, but she's got the foam roller under her side. Future Olympian, that girl. She loves to run fast.
